The next History of Humanities and Sciences Meeting will take place on Monday 7 December, with two talks on HHS -- ranging from Europe to Japan!

After the talks, we will give an update about the latest news on our Center. The Governing Board (CvB) of the UvA has decided last month to grant our subsidy request and we will start as an official Center for the History of Humanities and Sciences from 2016 onwards. This is great news, and we will celebrate the new Center with a major kick-off event in 2016. More news will follow soon. On December 7 we will already give some further details about our new course in HHS, our research program for the years to come, our ideas about the fellowship program, and our new collaboration between the Max Planck Institut für Wissenschaftsgeschichte and the UvA.

Different predicates give rise to different entailment patterns, both distributive and collective. Some predicates are ambiguous between distributive and collective readings. To complicate things further, in some cases two arguments of a predicate may be interpreted distributively: such readings are affected not only by the predicate, but also by the argument.

In this talk I present various entailment patterns which emerge as a result of properties of nominal expressions, and describe several attempts to derive these patterns in an algebraic (mereological) framework. Finally, I demonstrate where these analyses fail, and what may be a possible solution.

We are inviting participants for the workshop "Projection in Discourse: from formal to data-driven approaches”, held on Friday November 27 at the University of Groningen, the Netherlands, on the occasion of Noortje Venhuizen's PhD defense. The aim of this workshop is to bring together current theoretical and empirical analyses of the behaviour of different types of projection phenomena, and their relation to other aspects of meaning. Besides several invited talks, the workshop will include a "data-driven" session, in which the participants are invited to collaborate on the analysis of real-life linguistic examples.

Attending the workshop is free, but we kindly ask you to register before Friday, November 20, via the registration form on the website.

Via this workshop, we are creating a forum to exchange ideas and explore new territory in which it is clear that logic can make a difference. We are particularly interested in the interplay between logic and the social sciences, i.e. both in studying complex social-epistemic scenarios as well as in the logical tools and techniques that can be used to model them. We approach the theme of this workhop from an interdisciplinary angle, and welcome any insights on to the topic coming from areas such as Logic, Game Theory, Belief Revision Theory, Formal Epistemology, Social Science, Cognitive Science and AI (multi-agent systems).

I will introduce the first-order languages L2 and Lt (from 'Topological model theory' by Flum and Ziegler), and the modal language Lm with derivative and counting operators. I will then illustrate original work which establishes the equivalence between Lt and Lm over T3 spaces, and that the result fails over T2 spaces. I will then present a recent axiomatisation of the Lm theory of the classes of all T3, T2, and T1 spaces. I will then discuss the open problem of proving that Lm enriched with only finitely many other modal operators is still less expressive than Lt over T2 spaces, and present some partial results. Finally, I will conclude by illustrating possible directions of future work.

Enqvist: I present some recent joint work with Fatemeh Seifan and Yde Venema, in which we introduced monadic second-order logic interpreted on coalgebras. Our main results provided conditions under which the coalgebraic modal mu-calculus for a given functor is the bisimulation invariant fragment of the corresponding MSO language. The focus of the talk will be on some open problems related to this topic.

Abstract:
An answer to this question depends on what kind of modality (logical, physical or biological) is in play: Flying pigs do not violate any logical or physical laws; therefore, it is logically and physically possible that pigs fly (think of very tiny pigs with large wingspans). However, there are no biological laws; it is hence either trivial that flying pigs are biologically possible, or an answer is more complicated. In this talk, we will explore the second option. We will first get acquainted with one of the very few explicit definitions of biological possibility which is due to Daniel Dennett and based on the Library of Mendel thought experiment. Second, we will see how the Library of Mendel can be used as stepping stone for logical models of pig mutants. Time permitting, we will have a more detailed look at one such model constructed in the framework of graded modal logic.

In the early 1900s, some paradoxes were discovered regarding the notion of truth. This led some philosophers to suggest abandoning truth entirely. However, Tarski's ground breaking paper “The concept of truth in formalized languages” (1935) reintroduced the concept of truth as a respectable notion. He introduced the notion of metalanguage and object language to avoid the paradoxes. This also led to a view called deflationism. Deflationism is a view that the assertion of truth should not assert more than the statement itself.

Since then, there have been attempts to formalise the concept of truth. There are two ways of formalising the concept: semantic and axiomatic theories of truth. Semantic theories use models of formal theories to state whether a sentence is true or false. This is generally accepted and used in model theory. Axiomatic theories introduce truth into the language of the theory.

We will use Peano Arithmetic (PA) as our base theory, the theory of the object language. We can show Goedel's theorems in PA and discuss truth in arithmetic. To respect deflationists' view on truth, I will introduce proof theoretic and model theoretic conservativities, and discuss the compositional axioms of truth.

Epistemic planning is an adaptation of a field in artificial intelligence, called automated planning, which develops algorithms that find plans that an agent can follow to reach his goal. Epistemic planning has the same intentions, but uses dynamic epistemic logic to define the planning problems and the plans, using the knowledge of the agent in the definition of a solution. I will present (part of) my thesis, where I extended epistemic planning to be able to deal with multiple acting agents, rather than just one. I will present the framework I developed, consisting of action control models and static control models, which are a combination of the standard models of DEL (Dynamic Epistemic Logic) and a semantic interpretation of STIT (seeing to it that), and I introduce a logic that talks about the knowledge of (coalitions of) agents and their power, and I show how this framework can be used to define a solution to multi-agent planning problems. Time permitting, I will also introduce a way for the agents to commit to certain actions, thereby enabling a group of agents to coordinate on which joint action to take.

Abstract:
A major reason why logic courses 'work' is that audiences worldwide feel an intuitive resonance with examples of correct and incorrect reasoning. Moreover, many people derive pleasure from exercising their logical skills: I will give a recent internet example that went viral, Cheryl's Birthday. But what is this logical talent, how far does it reach, and how did its academic study originate?

I will discuss a few issues by means of examples:
* Where logic occurs in human cognitive behavior (it is really a family of skills),
* How (or to what extent) reasoning is entangled with language,
* How logical theory arose, and what role it plays in the above.
This lecture is a light introduction to these topics.

We use the entanglement sampling techniques developed in (Dupuis et al., 2015) to find a lower bound on the entanglement needed by a coalition of cheaters attacking the quantum postition verification protocol using the four BB84 states (QPVBB84) in the scenario where the cheaters have no access to a quantum channel but share a (possibly mixed) entangled state Φ. For a protocol using n qubits, a necessary condition for cheating is that the max-relative entropy of entanglement E_max(Φ) ≥ n − O(log n). This improves previously known best lower bound by a factor approx. 4, and it is essentially tight, since the protocol is vulnerable to a teleportation-based attack using n − O(1) ebits of entanglement.

The workshop is free and you can simply turn up on the day, but if you are definitely planning to attend please email Luca Incurvati. For more information, please contact L.Incurvati at uva.nl.

The Parallel Repetition Theorem is an important tool in complexity theory and cryptography, used to amplify the hardness of multiplayer games. It roughly states that if a game G, involving two non-communicating players, has value p, then the two-player game G^n -- n independent instances of G in parallel -- has value f(p,G)^n, where f(p,G) is some (complicated) function of p and the game. Recently, there has been much interest in proving a quantum analogue of the Parallel Repetition Theorem, where the players are allowed to use quantum entanglement as part of their strategy. We give improved parallel repetition theorems for entangled games in the case that the players' inputs are uncorrelated.

Descriptive set theory (DST) is the study of the definable sets of real numbers and similar topological spaces. One of DST's main driving questions is: What can we say about a set if all that we know is that it is definable with a certain complexity? For example, we know that if a set is the projection of a closed subset of the real plane then it cannot be a counterexample to the Continuum Hypothesis. On the other hand, the usual axioms of set theory don't determine whether the same can be said of all *complements* of such sets!
One especially interesting space studied in DST is the Baire space, composed of the infinite sequences of natural numbers. The topology of this space has a certain computational-combinatorial flavor which makes many arguments more intuitive than in other spaces. Another nice aspect of this space is that it lends itself quite naturally to analysis by infinite games, which I hope to convince you of in this talk.
I will start with a brief description of some games which have far-reaching consequences for set theory and the foundation of mathematics. The main focus of the talk will be the games which characterize interesting classes of functions in Baire space, where I will describe results by Wadge, Duparc, Andretta, Semmes, and (time permitting) yours truly. I will assume no prior knowledge other than some basic mathematics, such as the definition of a topology.

Abstract:
In this presentation I focus on the 'epistemic potential' of a group of agents, i.e. the knowledge (or beliefs) that the group may come to possess if all its members join their forces and share their individual information. Among the different notions of group knowledge studied in the literature, which one can give us a good measure of a group'sepistemic potential? Hence, when exactly is the group's ability to track the truth higher than that of each of its members? I will answer these questions by paying attention to a number of different factors that may play a role, including: the group's dynamics, the structure of the social network, the individuals' different epistemic interests and agendas, etc. When we take these realistic conditions into account, an accurate formalization of a group's potential knowledge can be developed. I will illustrate the setting with examples from interrogative scenarios in which we allow inter-agent communication as the group's main knowledge-aggregation method.The results reported on in this lecture are based on on-going joint work with A. Baltag and R. Boddy.

In this talk, we will construct the set of Hyperreal Numbers using the help of Model Theory. The set of Hyperreal Numbers is a field containing real numbers with the addition of "infinitely small" and "infinitely big" numbers.

We will begin with some historical background of Newton's (and Leibniz's, as well) work (differentiation) and why he needed the concept of "infinitely small" numbers. Then to construct the set of Hyperreal Numbers, we will introduce some Model Theoretic concepts (such as languages, structures, sentences and elementarily equivalence) and Los's Theorem. Then, we will construct the nonstandard extension of the set of real numbers which we will call "the set of Hyperreal Numbers" and we will proceed with examples of some actual hyperreal numbers and the extensions of some classical functions from standard analysis, such as exponential function and trigonometric functions. If time permits, we will see some basic theorems in Nonstandard Analysis, such as Robinson's Compactness Criterion.

Abstract:
In the work of the game theorist Françoise Forges, nonsignalling correlations independently appear under the name of "belief-invariant communication equilibria". The motivation and the use of these objects are different than what we would expect in quantum information. Here, we explain and unify the two views and introduce the concept of "privacy compatible correlated equilibrium". We model, for example, situations where competing companies benefit from a correlated strategy, without revealing their trade secrets (seen as private inputs).
This is work in progress, together with Andreas Winter (UAB Barcelona) and Ashutosh Rai (University of Latvia).

In this talk, I will briefly introduce the theory and practice of Coq - a proof assistant based on dependent type theory. A proof assistant is a piece of software that provides you with a semi-interactive environment for constructing and verifying formal proofs. Coq has been used to prove/verify theorems from "pure math" (e.g. odd order theorem), as well as in software verification (verified C compiler).

Feel free to bring your laptops, as the second part of the talk will be a practical hands-on Coq session, during which we will play a bit with Coq, by defining basic datatypes and proving simple properties about them.

Abstract: We investigate the possibility of constructing tamper-resistant cryptographic devices using quantum mechanics. In particular, we consider "one-time programs" -- programs that can be run only once, and reveal nothing about their internal structure. It is known that one-time programs can be constructed using "one-time memories" -- a simpler class of devices related to oblivious transfer. We show how one-time memories can be built using "isolated qubits" -- qubits that have long coherence times, but can only be accessed using single-qubit gates and measurements; entangling operations are not allowed. Our construction achieves information-theoretic security based on a clear physical assumption, and is potentially realizable using near-future technologies such as solid-state qubits.

Researchers from various UvA departments share a deep interest in the study of decision making and decision support. Joining forces would enable researchers with backgrounds in, e.g., Psychology, Economics, Biology, Mathematics, Logic, Artificial Intelligence, and Computer Science to capitalize on their complementary expertise. This, in turn, will allow the UvA to widen the interdisciplinary nature, scope, and significance of ongoing research in the decision sciences, and to educate a new generation of experts in this field. The Symposium on Decision Making will bring together UvA staff members and students from various departments and Master's programmes to discuss central questions, share perspectives, and identify common ground as well as important focus topics for potential research and education initiatives, in an interactive forum.

The programme will consist of a keynote lecture by Paul Glimcher (NYU) on neuroeconomics and three panel discussions on different questions related to decision making and decision support.

What is logic, really? Now often thought of as a relatively independent branch of mathematics, logic was in fact for large parts of its history seen as a kind of personal self-improvement tool used to teach oneself proper habits of rational thought.

In my presentation, I will give examples of what this meant for the way logic books were written and used in early modern Europe. From the 17th century onwards, the emerging middle classes borrowed highly selectively from the medieval scholastic tradition in an effort to forge a new secular rationality that could match their increasingly confident class consciousness.

After giving examples of this trend, I will follow the history of that tradition up to the emergence of mathematical statistics, which in the 19th century largely replaced logic as the marker of "Rational Man." Reconstructing this history sheds some new light on the surprisingly virulent disagreements in 20th century statistics.

Though projection is the characteristic property of presuppositions, projection from the scope of a quantifier has remained a problem. Experimental evidence has corroborated differences between quantifiers (Chemla 2009, Nat. Lang. Sem.). We propose a new approach based on the idea that silent domain restriction is generally allowed, but must satisfy the strongest meaning principle. Our system makes more accurate predictions than Fox (2013, in Camb. Univ. Press volume) "Strong Kleene" Semantics, however, for modified numerals a combined system seems to fare best.

We consider the properties of the arithmetically simplest class of universal (i.e. $\Pi^0_1$) sentences undecidable in sufficiently strong arithmetical theories. Following the framework of experimental logic and results of R. G. Jeroslow obtained in Jer75, we therefore answer an epistemological question about cognitive reasons of epistemic hardness of undecidable arithmetical sentences. We prove that by adjoining the minimal (in the sense of being on a very low level of arithmetical hierarchy) possible set of undecidable sentences to recursive set of axioms of arithmetical theory and closing it under logical consequence, we obtain a theory such that it is not algorithmically learnable (i.e. not $\Delta^0_2$).

SMART Cognitive Science is an initiative of the Faculty of Humanities of the University of Amsterdam to provide a forum for the discussions highlighting the important contributions to cognitive science from traditional humanities disciplines. SMART is an acronym for Speech & language, Music, Art, Reasoning & Thought. The SMART Cognitive Science International Conference will consist of three plenary evening lectures and six 2-day workshops devoted to the topics on the intersection of humanities and cognitive science.

For more information, see http://smartcs.humanities.uva.nl/.

A fundamental observation about human cognition is that we make "infinite use of finite means," using a limited number of rules and principles to generate unbounded sets of behaviors and to recognize unbounded sets of patterns. In many cases this involves a capacity to both generate and perceive tree structures in stimuli of various types (language, music, social cognition, etc.). Human language in particular requires computational resources that go beyond simple string generation to allow the inference and generation of complex, flexible tree structures. This entails supra-regular (above finite state) computational mechanisms that augment standard finite state mechanisms with a flexible, multi-purpose memory store (a "stack" or equivalent).

I review comparative research gathered over the past decade suggesting that such computational resources are poorly developed or absent in most nonhuman animal species. This body of empirical research implies that the human proclivity for producing and perceiving tree-structured stimuli -- our "dendrophilia" -- represented a key cognitive innovation during recent human evolution. Both brain imaging and comparative research suggest that Broca's area (Brodmann Areas 44 and 45) is an important computational hub for human tree processing, suggesting that this core prefrontal region was harnessed, and its computational role expanded, during the evolution of dendrophilia and human cognitive abilities in general.

In this talk, I will introduce you to the ontological argument for the existence of God: Its birth in the Middle Ages, its apparent death in the Age of Enlightenment and Gödel's (in)famous ontological proof as an example of its phoenix-like resurrection in our age. To him, the ontological argument posed a logical challenge, namely, "in showing that such a proof with classical assumptions (completeness, etc.) correspondingly axiomatized, is possible." I will walk you through his formal proof in detail.

In this (tutorial) talk we present some of the usual (very) large cardinals, which are those described by the existence of elementary embeddings between transitive class models of ZFC set theory. We look at some standard results and techniques in the context of such elementary embeddings. Subsequently, we introduce the hierarchies of C^(n)-cardinals, which were defined and studied by Bagaria, giving an overview of their properties and connections with the usual large cardinal hierarchy. Finally, we mention some recent applications of C^(n)-cardinals outside of set theory. (The talk is meant to be accessible to master level students.)

Abstract: This lecture will be an introduction to the theory of judgment aggregation (JA). JA deals with the problem of combining the views of several individual agents regarding the truth of a number of propositions, expressed in the language of logic, into a single such view that appropriately reflects the stance of the group as a whole. Applications of JA range from aggregating the opinions of several judges in a court of law into a single legal opinion, all the way to aggregating information received from several autonomous software agents in the context of distributed computing systems.

Abstract: Logical consequences can be viewed as informational dependencies that would also hold in a world empty of people. While consequence is the basis for logic, human agents engage in styles of reasoning, of which I will discuss a few: mathematical proof generating knowledge, default inferences generating beliefs, and of course interactive argumentation where we try to persuade as well as convince. The surprising fact is that logical methods can also help model this wider world of intellectual abilities. In addition, if time permits, I will consider another key feature of human reasoning: its resource-boundedness, and what this means for the actual 'natural logic' we have available for 'thinking fast' in decisions, as opposed to the 'thinking slow' of long-term deliberation, and research.

Abstract: Hash-based signatures are currently the most confidence-inspiring replacement for the signature schemes used today. Their security is solely based on the security of the used hash function(s) and can be related to the same by means of standard-model security reductions. Today's hash-based signature schemes have performance close to that of RSA & Co and are currently subject to standardization. The only drawback of hash-based signature schemes in practice is that they are stateful, i.e., the secret key has to be updated after each signature. However, recent results show that this problem can actually be solved while maintaining practical performance and reliable security. This talk will discuss the basics of hash-based signature schemes. It will cover one-time and many-time signature schemes, Lamports scheme, the Winternitz OTS, Merkle's scheme, and XMSS. Finally, it will be explained how to build practical stateless hash-based signature schemes, explaining the concept of few-time signature schemes and introducing SPHINCS.

The Intelligent Narrative Technologies (INT) workshop series aims to advance research in artificial intelligence for the computational understanding and expression of narrative. INT8, the eighth workshop in the series, will be co-located with the Eleventh Annual AAAI Conference on Artificial Intelligence and Interactive Digital Entertainment (AIIDE 2015) at University of California, Santa Cruz.

Recent years have witnessed significant advances in the technical, creative, and aesthetic interpretation of narratives with digital media, including games, simulations, interactive fiction, and electronic literature. Our goal is to contribute to this forward momentum by congregating a multidisciplinary group of researchers and practitioners to share their latest work at the intersection of narrative and technology. Previous meetings of this workshop have brought together computer scientists, psychologists, narrative theorists, media theorists, artists, writers, and members of the interactive entertainment industry. From this broad expertise, the workshop focuses on computational systems to represent, reason about, create, adapt, and perform interactive and non-interactive narrative experiences. This also includes fundamental research in relevant fields such as natural language processing, believable virtual characters, commonsense reasoning, computer vision, computational media, and human storytelling.

Agent-based Computing addresses the challenges in managing distributed computing systems and networks through monitoring, communication, consensus-based decision-making and coordinated actuation. As a result, intelligent agents and multi-agent systems have demonstrated the capability to use intelligence, knowledge representation and reasoning, and other social metaphors like 'trust', 'game' and 'institution', not only to address real-world problems in a human-like way but also to transcend human performance. This has had a transformative impact in many application domains, particularly in e-commerce, and also in planning, logistics, manufacturing, robotics, decision support, transportation, entertainment, emergency relief & disaster management, and data mining & analytics.

Ever since philosophers first started formulating theories of science those theories have been compared with (reconstructions of) episodes in the history of science. On this issue one finds heated discussion in the 1960s and 70s, when some sought to turn philosophy into a testable enterprise, with history taking the place of scientific experiment. The purpose of this workshop is to bring this debate back to the table, assessing it in light of the fact that so many contemporary debates in the philosophy of science make implicit assumptions about how history of science can bear on philosophy of science.

This is a one-day workshop, 21st September 2015, organised by The Oulu Centre for Theoretical and Philosophical Studies of History and the AHRC project 'Contemporary Scientific Realism and the Challenge from the History of Science. The event is designed to bring together historians and philosophers of science. Keynote Speakers: James McAllister (Leiden), Helge Kragh (Aarhus), Katherina Kinzel (Vienna) and Bart Karstens (Amsterdam).

The Hyperuniverse Programme, launched in 2012, and currently pursued within a Templeton-funded research project at the Kurt Gödel Research Center in Vienna, aims to identify and philosophically motivate the adoption of new set-theoretic axioms.

The programme intersects several topics in the philosophy of set theory and of mathematics, such as the nature of mathematical (set-theoretic) truth, the universe/multiverse dichotomy, the alternative conceptions of the set-theoretic multiverse, the conceptual and epistemological status of new axioms and their alternative justificatory frameworks.

The aim of SotFoM III+The Hyperuniverse Programme Joint Conference is to bring together scholars who, over the last years, have contributed mathematically and philosophically to the ongoing work and debate on the foundations and the philosophy of set theory, in particular, to the understanding and the elucidation of the aforementioned topics. The three-day conference, taking place September 21-23 at the KGRC in Vienna, will feature invited and contributed speakers.

Strategic reasoning is one of the most active research areas in the multi-agent system domain. The literature in this field is extensive and provides a plethora of logics for modelling strategic ability. Theoretical results are now being used in many exciting domains, including software tools for information system security, robot teams with sophisticated adaptive strategies, and automatic players capable of beating expert human adversary, just to cite a few. All these examples share the challenge of developing novel theories and tools for agent strategies that take into account the likely behaviour of adversaries. The SR international workshop aims to bring together researchers working on different aspects of strategic reasoning in computer science, artificial intelligence and multi-agent systems research, both from a theoretical and a practical viewpoint.

Improved computational models of semantics hold great promise for applications in language technology, be it semantics at the lexical level, sentence level or discourse level. Large-scale corpora with corresponding annotations (word senses, propositions, attributions and discourse relations) are making it possible to develop statistical models for many tasks and applications. However, developments in lexical and sentence-level semantics remain largely distinct from those in discourse semantics. This workshop aims at bridging this gap by bringing together researchers to discuss how multiple levels of semantics can be integrated and implemented in various applications.

Our goal is to gather and showcase theoretical and computational approaches to joint models of semantics, and applications that incorporate multi-level semantics. We hope to bring together researchers from various areas: computational linguistics who strive for more expressive models of language understanding, linguists and cognitive scientists interested in aspects of representing text with multiple levels of semantics, machine learning researchers interested in joint inference over different types of semantic cues, and also researchers who are interested in applications that require or will benefit from multi-level semantics. A dialog between researchers has great potential to advance work in each of these areas and bring about more powerful and enriched models of text semantics.

The second edition of the FILOMENA Workshop (FIlosofia, LOgica e MEtafísica aNAlítica), promoted by the Group on Logic and Formal Philosophy from the UFRN, has the purpose of gathering logicians working at the intersection of Logic and Metaphysics, through the application of formal methods in Philosophy.

Logic, while initially considered as a branch of Philosophy, has outgrown its original purposes and found connections with other areas of Philosophy, such as Philosophy of Language, Philosophy of Mathematics, Philosophy of Science and Philosophy of Mind. Since its modern development, Logic has proved to be a powerful tool for analyzing different philosophical theories, as well as their foundations and implications; moreover, the birth and development of non-classical logics has expanded its domain of application much beyond the dreams of its progenitors.

As part of the celebrations of Boole's bicentenary, the George Boole Mathematical Sciences (GBMS) Conference will be held in University College Cork (UCC) during the last two weeks of August 2015. George Boole (1815 ' 1864) was the first professor of mathematics at Cork. Boole's efforts to mathematize logical thinking caused a lasting paradigm shift in the 19th century which enlarged the scope and potency of modern mathematics, and provided a wealth of ideas for applications in diverse scientific areas resulting in ground-breaking innovations during the 20th century and beyond.

This event will include 100-150 lectures on selected areas, and embed the folllowing events:
- 2015 Annual Meeting of the Irish Mathematical Society (IMS)
- Domains XII
- When Boole Meets Shannon

This workshop provides a forum for discussion of recent empirical advances in categorial grammar (CG). After the revival of interest in CG in linguistics in the 80s, various extensions to the Lambek calculus and an early version of Combinatory Categorial Grammar have been proposed. But the fundamental question of whether CG constitutes an adequate linguistic theory still seems to be wide open. Moreover, there are now numerous variants of CG, both in the TLCG tradition and in CCG. Which of these theories constitutes the most adequate version of an empirical theory of natural language?

Logical, mathematical, and computational analyses have tended to take precedence over empirical ones in the past 30 years in CG research. These are all important and very illuminating, but at the same time we may now want to pause and reflect on the question of just where we are in terms of empirical adequacy. We think that the time is ripe to critically scrutinize the empirical consequences of the various formal techniques/frameworks proposed in the literature in the past 30 years, as well as ones that are being developed at this very moment.

Research in resource-bounded agency contributes both to reasoning about actions in philosophy and artificial intelligence, and to applications of logic in computer science, such as the practical verification of resource-bounded multi-agent systems. The Logics for Resource-Bounded Agents workshop will provide a forum for established researchers and advanced PhD students to present and discuss their work with colleagues working in related areas (particularly those represented at ESSLLI). In addition to logics of strategic ability where actions produce and consume resources, we solicit contributions from researchers working in epistemic logic, game theory, linear logic etc. on alternative approaches to modelling resource-bounded agency.

The workshop is part of ESSLLI and is open to all ESSLLI participants. It will consist of five 90-minute sessions held over five consecutive days in the second week of ESSLLI. There will be 2 or 3 slots for paper presentation and discussion per session. On the first day the workshop organizers will give an introduction to the topic.

For more information, see http://www.cs.nott.ac.uk/~nza/lrba15/

Recent years have seen increased interest in applying logical methods and frameworks, the traditional subject matter of ESSLLI, to cognitive modeling, whereby logical models of cognitive phenomena are tested against empirical data. At the same time, there has recently been an explosion of activity in the cognitive sciences around (structured) statistical, and specifically Bayesian, models. With this workshop we propose to bring together two groups of researchers -- logicians focused on cognitive modeling, and cognitive scientists incorporating logical structure into probabilistic models -- with the aim of cross-pollination, and ideally, a consensus on how these two traditions relate, and how we might combine the best of what both have to offer. The primary aim is to gain a better understanding of (i) how cognitive computational models could be enriched by logical insights and (ii) how logical models may be turned into cognitive models.

The Student Session of the 27th European Summer School in Logic, Language, and Information (ESSLLI) will take place in Barcelona, Spain, August 3rd to 14th. We invite submissions of original, unpublished work from students in any area at the intersection of Logic & Language, Language & Computation, or Logic & Computation. Submissions will be reviewed by several experts in the field, and accepted papers will be presented orally or as posters and will appear in the student session proceedings by Springer. This is an excellent opportunity to receive valuable feedback from expert readers and to present your work to a diverse audience.

Note that there are two separate kinds of submissions, one for oral presentations and one for posters. This means that papers are directly submitted either as oral presentations or as poster presentations. Reviewing and ranking will be done separately. We particularly encourage submissions for posters, as they offer an excellent opportunity to present smaller research projects and research in progress.

Submission deadline: March 25, 2015. Detailed guidelines regarding submission can be found on the Student Session website: http://esslli-stus-2015.phil.hhu.de/. Please direct inquiries about submission procedures or other matters relating to the Student Session to P.Schulz at uva.nl and kaeshammer at phil.uni-duesseldorf.de.

Quantifiers play an important role in language extensions of many logics. The use of quantifiers often allows for a more succinct encoding as it would be possible without quantifiers. However, the introduction of quantifiers affects the complexity of the extended formalism in general. Consequently, theoretical results established for the quantifier-free formalism may not directly be transferred to the quantified case. Further, techniques successfully implemented in reasoning tools for quantifier-free formulas cannot directly be lifted to a quantified version.

The goal of the 2nd International Workshop on Quantification (QUANTIFY 2015) is to bring together researchers who investigate the impact of quantification from a theoretical as well as from a practical point of view. Quantification is a topic in different research areas such as in SAT in terms of QBF, in CSP in terms of QCSP, in SMT, etc. This workshop has the aim to provide an interdisciplinary forum where researchers of various fields may exchange their experiences.

Logic was originally meant to systematize and analyze arguments in natural language. But in the 20th century the main developments in logic focused on mathematics and its foundations. Recently, a number of researchers have focused on logical systems tuned to natural language semantics to reconnect with the older tradition. The logical and conceptual underpinnings of some of these systems remains unclear, although some recent work has begun to address formal foundations.

The aim of this conference is to contribute to this direction in semantics and to discuss logics, especially proof systems, well-suited for natural language semantics and to explore comparisons between these systems. We also welcome input from people invoved in computational semantics, psychology of reasoning, and computer implementations of natural reasoning systems.

Most Program Verification and Synthesis problems of interest can be modeled directly using Horn clauses and many recent advances in the CLP and CAV communities have centered around efficiently solving problems presented as Horn clauses.

This workshop aims to bring together researchers working in the two communities of Constraint/Logic Programming (e.g., ICLP and CP) and Program Verification community (e.g., CAV, TACAS, and VMCAI) on the topic of Horn clause based analysis, verification and synthesis. Horn clauses for verification and synthesis have been advocated by these two communities in different times and from different perspectives and this workshop is organized to stimulate interaction and a fruitful exchange and integration of experiences.

This workshop brings together researchers working on mathematical foundations of quantum physics, quantum computing, spatio-temporal causal structures, and related areas such as computational linguistics. Of particular interest are topics that use logical tools, ordered algebraic and category-theoretic structures, formal languages, semantical methods and other computer science methods for the study of physical behaviour in general. The workshop will be preceded by tutorials

For more information, see http://www.cs.ox.ac.uk/qpl2015/

The conference is concerned with the theory of computability and complexity over real-valued data. The classical approach in these areas is to consider algorithms as operating on finite strings of symbols from a finite alphabet. Most mathematical models in physics and engineering, however, are based on the real number concept. Thus, a computability theory and a complexity theory over the real numbers and over more general continuous data structures is needed.

Despite remarkable progress in recent years many important fundamental problems have not yet been studied, and presumably numerous unexpected and surprising results are waiting to be detected. Scientists working in the area of computation on real-valued data come from different fields, such as theoretical computer science, domain theory, logic, constructive mathematics, computer arithmetic, numerical mathematics and all branches of analysis.

Formal tools coming from logic and category theory are important in both natural language semantics and in computational semantics. Moreover, work on these tools borrows heavily from all areas of theoretical computer science. In the other direction, applications having to do with natural language has inspired developments on the formal side. The workshop invites papers on both topics.

MC'15 is affiliated with 42nd International Colloquium on Automata, Languages and Programming (ICALP 2015) and 30th Annual ACM/IEEE Symposium on Logic in Computer Science (LICS 2015)

The formal analysis of ethical concepts and theories (via the application of tools from logic, rational choice theory, natural language semantics, AI) is a rapidly growing field of research. It has shed new light on a variety of concepts that are central to ethical theory, such as freedom, responsibility, values, norms, and conventions. The series Formal Ethics conferences aims at providing an international platform for the discussion and promotion of formal approaches to ethics, to bring together researchers who are employing formal tools to address questions in ethics and/or political philosophy, and to push the frontiers of the research being conduced in this field.

Researchers in several communities are trying to understand the basic principles underlying creativity-related abilities (such as concept invention, concept formation, creative problem solving, the production of art, and creativity in all its facets e.g. in engineering, science, mathematics, business processes), working on computational models of their functioning, and also their utilization in different contexts and applications (e.g. applications of computational creativity frameworks with respect to mathematical invention and inventions in engineering, to the creation of poems, drawings, and music, to product design and development, to architecture etc.). In particular, a variety of different methodologies are used in such contexts ranging from logic-based frameworks to probabilistic and neuro-inspired approaches. This workshop shall offer a platform for scientists and professional users within relevant areas, on the one hand presenting actual and ongoing work in research, on the other hand also offering a chance for obtaining feedback and input from applications and use-case studies.

CiE 2015 is the 11-th conference organized by CiE (Computability in Europe), a European association of mathematicians, logicians, computer scientists, philosophers, physicists and others interested in new developments in computability and their underlying significance for the real world.

Evolution of the universe, and us within it, invite a parallel evolution in understanding. The CiE agenda - fundamental and engaged - targets the extracting and developing of computational models basic to current challenges. From the origins of life, to the understanding of human mentality, to the characterising of quantum randomness - computability theoretic questions arise in many guises. The CiE community, this coming year meeting for the first time in Bucharest, carries forward the search for coherence, depth and new thinking across this rich and vital field of research.

There is an ongoing philosophical and logical debate about motivations in accepting or rejecting the principle (law) of (non-)contradiction and the principle (law) of excluded middle. A logic rejecting the principle of non-contradiction is called *paraconsistent* and a logic rejecting the principle of excluded middle is called *paracomplete*. But what does it really mean to reject a classical principle (law)? And what are the philosophical consequences for this refusal? In which sense would it still be possible to defend nowadays that there is just one true logic?

This workshop, held at the 5th World Congress on Universal Logic in Istanbul, shall represent a privileged platform to evaluate proposals for a more integrated and general approach to philosophical motivations and consequences in the emergence of non-classical logics. Keynote speaker: Graham Priest (CUNY).

Logic as a discipline is not characterized by a stable scope throughout its history. True enough, the historical influence of Aristotelian logic over the centuries is something of a common denominator in Western philosophy. But Aristotelian logic certainly was not alone (see stoic logic for instance), not to mention non-western logics. Even within the Aristotelian tradition there is significant variability. Furthermore, as is well known, in the 19th century logic as a discipline underwent a radical modification, with the development of mathematical logic. This workshop, held at the 5th World Congress on Universal Logic in Istanbul, will focus on both the diversity and the unity of logic through time.

Since 1995, the NLDB conference aims at bringing together researchers, industrials and potential users interested in various applications of Natural Language in the Database and Information Systems field. The integration of databases and natural language has been an utopia for many years. However, progress has been made and this is now an established field thanks to developments in Natural Language and technologies that made the storage and manipulation of large linguistic resources and datasets possible. The use of Natural Language in Software Engineering has contributed to both improving the development process from the viewpoints of developers (improve the process of conceptual modeling, validation, etc) and the usability of applications by users (natural language query interfaces, etc). NLDB'15 will take place in Passau, Germany.

Studying logics via semantics is a well-established and very active branch of mathematical logic, with many applications, in computer science and elsewhere. The area is characterised by results, tools and techniques stemming from various fields, including universal algebra, topology, category theory, order, and model theory. The programme of the conference TACL 2015 will focus on three interconnecting mathematical themes central to the semantic study of logics and their applications: algebraic, categorical, and topological methods. This is the seventh conference in the series Topology, Algebra, and Categories in Logic (TACL).

Starting from 2013, the conference TACL -Topology, Algebra, and Categories in Logic- is preceded by a one-week school. In 2015 the school will be held at the campus of the University of Salerno and will include four tutorials, each consisting of 1.5 hour lectures for five days.

The 20th century has witnessed several attempts to build (parts of) mathematics on grounds other than those provided by classical logic. The goal of this seminar, along with presenting recent advances in particular areas (see the list of topics below), is to provide an opportunity for round-table discussions about the common aspects of various `non-classical' approaches, including similarities between results, proof methods, and methodological questions about the role of classical logic/mathematics in our work.

The European Conference on Argumentation (ECA) is a new pan-European initiative aiming to consolidate and advance various streaks of research into argumentation and reasoning: from philosophical, linguistic, discourse analytic, cognitive, to computational approaches. The chief goal of the initiative is to organize on a regular basis a major conference on argumentation. The first of these conferences will be hosted in Lisbon by the ArgLab, Institute of Philosophy (IFILNOVA), Universidade Nova de Lisboa.

The primary idea behind this first edition of the conference is that argumentation and reasoning are the main vehicles for our decisions and actions. They accompany, indeed constitute, a variety of significant social practices: from individual practical reasoning, small group decisions, deliberations of official bodies in various institutional contexts, to large-scale political and social deliberations. Argumentation is understood here as a mode of action - and not just any action, but a reasoned action, comprised of consideration of reasons (whether they are good or bad). Traditionally, argumentation has been assigned many distinct functions: epistemic, moral, conversational, etc. The aim of the conference is to explore how these functions are interrelated with the practical need for deciding on a course of action. Simply put, our chief concern is with the role argumentation and reasoning play when the question of 'what to do?' is addressed.

The study of the logical foundations of topology is playing an important role in mathematical logic and foundations of especially constructive mathematics. Early works by Brouwer on the theory of spreads and choice sequences were influencing much work in the area. A modernized form of his ideas is embodied in constructive point-free topology or formal topology. The workshop will gather experts in this field and related areas, including computable aspects and non-classical aspects of topology. A subtheme will be modern developments in the theory of spreads and choice sequences, as well as its history.

This is the fifth of a series of successful meetings on the development of Formal Topology and its connections with related approaches. The workshop is part of the Institut Mittag-Leffler short conferences program 2015. The number of participants is limited to 30 due to reasons of space.

Narrative provides a framing structure for understanding, communicating, influencing, and organizing human experience. Systems for its analysis and production are increasingly found embedded in devices and processes, influencing decision-making in venues as diverse as politics, economics, intelligence, and cultural production. This inter-disciplinary workshop will be an appropriate venue for papers addressing fundamental topics and questions regarding narrative, such as the technical implementation of narrative systems, the theoretical bases of these frameworks, and our general understanding of narrative at multiple levels: from the psychological and cognitive impact of narratives to our ability to model narrative responses computationally.

CMN 2015 will be co-located with the Third Annual Conference on Advances in Cognitive Systems (ACS 2015). The workshop will have a special focus on the building cognitive systems that are distinguished by a focus on high-level cognition and decision making, reliance on rich, structured representations, a systems-level perspective, use of heuristics to handle complexity, and incorporation of insights about human thinking, meaning we especially welcome papers relevant to the cognitive aspects of narrative.

Historians of logic have known for decades that the 14th century was a tremendously productive period in the Latin West. As far as the relationship between logic and metaphysics is concerned, however, research has tended to focus on the nominalist tradition associated with Ockham and Buridan. The aim of this workshop is to redress the balance a little by focussing instead on the realist tradition that spans the 14th century. We have singled out for special mention the influential figure of John Wyclif, whose Logic is currently being re-edited here at St Andrews, but we welcome contributions involving other figures from Walter Burley to Paul of Venice.

Explanation is one of the central goals of scientific research and abduction is a type of inference in which explanation plays a key role. Thus far, most philosophers will agree. When we consider more specific claims, however, many questions are still open to debate. What are the different forms of explanation and of abduction? How do these interrelate? To what extent are they open for formal explication? What about the relation to other notions, such as confirmation, induction, IBE, causality, belief revision, ...? The aim of this interdisciplinary workshop is to further our understanding of these notions and of their interrelations.

Logic can be understood in different ways. The word "logic" has four basic meanings: reasoning, science, language and relation. Religion is also "relational", it can be viewed as the connection between human beings with life, reality, divinity. Logic, symbol of rationality, may appear as opposed to religion belief-oriented.

But logic and religion are intertwinned in many ways. Theo-logy is the science of god. It includes some proofs of the existence of god ranging from Anselm to Gödel. Moreover in the Bible the logos is assimilated to God and this has been repercuted in occidental philosophy in different ways by philosophers such as Leibniz or Hegel. A religion like Buddhism is also strongly connected to reasoning as well as Islam and many others.

This will be the first world congress on logic and religion. Relations between logic in all its dimensions - philosophical, mathematical, computational, linguistical - and the the different religions will be examined.

A research community that could be described with the phrase "Practice and Cultures of Mathematics" has studied mathematics as a human subject with different practices and cultures in recent years. This research has been closely linked to the Philosophy of Mathematical Practice community and its Association for the Philosophy of Mathematical Practice, but is broader in the sense that it is interested in the study of mathematical practices and cultures independently of whether there is an interaction with traditional philosophical questions (such as epistemology or ontology).

In addition to many other meetings associated to the research community, there has been a series of meetings dealing specifically with the phenomenon of diversity of research cultures in mathematics: the traditional view claims that all of the differences between mathematical research cultures are superficial and do not touch the nature of mathematics; it is the goal of this research community to evaluate that claim by studying concrete examples. Here, culture should be understood very widely, and cultural differences can be found distinguishing mathematical subdisciplines, national cultures, cultures imposed by university or institute structures, etc.

The meeting will focus on case studies from mathematical research that highlight cultural differences, methodological discussions of the use of empirical data from the study of mathematical practice for gaining insight in the phenomenon of mathematics, and fundamental questions about mathematics that require a view towards mathematics as a human discipline to be discussed.

- What are the roles of pictures and diagrams in mathematical proofs, in formal reasoning, and in epistemic justification more broadly?
- Can pictures by themselves serve as arguments insofar as they can be persuasive and even convey a sense of demonstrative certainty?
For the most part, these two questions have been discussed separately. We seek to bring them together and thereby take them in new directions. These are philosophical questions that are addressed by many different disciplines: STS, history of science, mathematics, engineering, media studies, and the visual arts. They draw attention to technologies of picturing, the contexts of practice in which proofs and procedures of formal reasoning are employed, and problems and methods of teaching and communication.

Semantics and pragmatics have long recognized multiple meaning types: asserted and entailed meaning, world knowledge and lexically based inferences, presupposition, expressive content, and conversational and conventional implicature. These each get their own separate treatments and/or are thought of as separate ~dimensions~ of meaning.

There are two main strands of research that question the traditional divisions: accounts that seek more unifying characteristics and accounts that identify exceptional behavior in a subset of a certain meaning type. The aim of the workshop is to discuss how to cut the pragmasemantic pie.

Invited Speakers: Craige Roberts, Judith Tonhauser, Hans-Martin Gärtner.

The conference will be devoted to the relationship between the semantics and pragmatics of logical constants (connectives, quantifiers, modal operators). Its aim is to critically assess and contribute to semantic and pragmatic theories developed for constructions containing such operators in natural language. On the one hand, we hope to bring together cutting edge contributions to debates that are currently in full swing, but at the same time, we very much invite contributions of a more historical nature, which shed light on antecedents of current views and issues, thereby placing them in a wider diachronic perspective. In short, the semantics and pragmatics of logical constants now and then.

Invited speakers:
* Rick Nouwen (Utrecht University)
* Daniel Rothschild (University College London)
* Johan van der Auwera (University of Antwerp)

Semantics is a divided discipline. On one side we have Formal Semantics, which has its roots in logic and analytical philosophy (Frege, Montague). Meaning here is viewed as a relation between language and external reality, formalized in terms of reference, truth, possible worlds, etc. On the other side we have Cognitive Semantics, a central part of the Cognitive Linguistics movement, which grew out of dissatisfaction with formal linguistics (in particular, formal semantics and generative syntax) in the seventies (Fauconnier, Lakoff, Talmy). In this framework meaning is primarily a relation between language and the mind, described in terms of mental spaces, conceptual schemata, frames, etc.

The focus of this conference is on different approaches to the foundations of mathematics. The interaction between set-theoretic and category-theoretic foundations has had significant philosophical impact, and represents a shift in attitudes towards the philosophy of mathematics. This conference will bring together leading scholars in these areas to showcase contemporary philosophical research on different approaches to the foundations of mathematics.

To accomplish this, the conference has the following general aims and objectives. First, to bring to a wider philosophical audience the different approaches that one can take to the foundations of mathematics. Second, to elucidate the pressing issues of meaning and truth that turn on these different approaches. And third, to address philosophical questions concerning the need for a foundation of mathematics, and whether or not either of these approaches can provide the necessary foundation.

The workshop will bring together the scholars who are either involved in the joint project “The Logical Dynamics of Information Exchange in Social Networks” (funded by the KNAW), or whose research is closely related to it. We aim to create a platform for researchers to exchange ideas and strengthen further collaboration.

With the KNAW project, the main research problem we want to investigate is the understanding of information flow and group belief dynamics in social networks. We intend to: (1) develop formal models and logics for the study of social-informational dynamics, (2) develop appropriate software for the computational analysis of this dynamics, (3) extract practical lessons about the opportunities and dangers posed by social networks, and (4) use these results as a source of philosophical reflection on the nature of social knowledge and the epistemological significance of corporate agents. The proposed methodology is to use extensions of Dynamic Epistemic Logic, in combination with probabilistic methods.

Jin Yuelin (1895—1984) was a pioneering philosopher and logician in China. After his study at Columbia University in the United States, he established the department of philosophy at Tsinghua University in 1926, where he started teaching modern logic for the first time, while engaged in deep encounters between modern and Chinese philosophy. Jun Yuelin's personality and ideas have had a continuing impact on logicians and philosophers in China right until today. In the spirit of Jin Yuelin's intellectual program, this international conference is held at Tsinghua University, exploring recent research into the many directions in his work and beyond. As our guiding theme, we will explore the current state of encounters between philosophy and logic. The conference will bring together Chinese and international scholars, both senior and junior.

RPPW is a biannual summit that seeks to explore innovative means of understanding rhythm production and perception. Rhythms are paramount in human functioning. Walking, talking, music performance – they all have rhythmic components. As of today the neurobiology of the underlying timing is not well understood, let alone the corresponding cognitive processes. The 15th edition of RPPW is therefore devoted to integrating various disciplines like biophysics, neurophysiology, cognitive psychology, and the science of music.

One of the central questions in philosophy of language and linguistic semantics in the 20th century was how we refer using proper names. Contemporary work on these issues is being conducted by both linguists and philosophers, and the nature of the topic and some of the recalcitrant problems facing extant accounts call for their collaborative interaction. Accordingly, our invited participants include scholars from both fields. The workshop will consist of six extended sessions over two days, each led by one of our invited speakers, with ample time for discussion and interaction with the distinguished group of invited discussants.

Please let us know by May 5th if you would like to attend, so we can plan accordingly. For more information and a registration form, see http://ias.ceu.edu/node/43092 or contact croberts at ling.osu.edu or zvolenszky at elte.hu.

Toy models are ubiquitous in the natural and social sciences - prominent examples include the Ising model in physics, the Lotka-Volterra model in the life sciences, and the Schelling model in the social sciences. It is characteristic of toy models that they simplify radically and often succeed in identifying the crucial features that produce a phenomenon. Toy models play an important and, though, insufficiently appreciated role in philosophy of science. This workshop addresses several questions regarding the epistemic functions of toy models in the natural and social sciences.

Massimiliano Carrara (University of Padua and COGITO) and Riccardo Pinosio (ILLC, University of Amsterdam) are organizing a Workshop "Logic from Descartes to Kant"

For more information, see here.

A conference in honor of Hugh Woodin's 60th birthday will be held at Harvard University on April 17-19, 2015.

The speakers for the meeting will be Garth Dales, Qi Feng, Matt Foreman, Alexander Kechris, Menachem Magidor, Donald Martin, Grigor Sargsyan, Ted Slaman and John Steel.

There is a conference website at:http://logic.harvard.edu/woodin_meeting.html Information will be added there as it becomes available. We would like to keep a head count of those planning to attend, so if you are planning to do so, please let us know at woodinbirthdayconference at gmail.com.

The role of logic can hardly be underestimated. On one hand, logical rules determine the basic canons of correct thinking. On the other, it is well known that very large portions of mathematics can be reconstructed only using logic and definitions. But what is logic? And how, if at all, can we know facts about logical validity? One promising starting point for answering these questions is the thought that logic, and our knowledge of it, are to be understood with reference to our *inferential practice*.

Accordingly, the conference focuses on the twofold inferentialist idea that the meaning of a logical expression is determined by the rules for its correct deductive use, and that to know the meaning of a logical expression is to know how to use it correctly. This very popular idea among philosophers has never been systematically explored. The main aim of the conference is to clarify the position, and to explore its attractive, if controversial, epistemological ramifications.

The Southeastern Logic Symposium 2015 will take place at University of Florida in Gainesville on the weekend of February 28/March 1, beginning with a colloquium talk on Friday February 27, 4pm. The main theme will be computability, descriptive set theory,and their interaction.

We have secured 25 prominent speakers for the conference. The plenary speakers include Denis Hirschfeldt, Andrew Marks, and Theodore Slaman; the Friday colloquium will be given by Henry Towsner. We do offer travel support for graduate students. We strongly encourage especially graduate students in set theory who wish to present a talk to apply.

For many applications, specific domain knowledge is required. Instead of coding such knowledge into a specific system in a way that it can never be changed (hidden in the overall implementation), different logic-based formalisms for representing different kinds of knowledge have been developed in the last 50 years. In this module, we discuss some of these approaches, namely modal logics and description logics.

Description logics are mainly designed to represent and reason about the terminology of an application domain and form the logical underpinning of the Semantic Web ontology language OWL. Modal logics can be used to represent and reason about the behaviour of systems, for example agent based systems. For both logics, automated reasoning tools have been developed to answer queries about the knowledge representation explicitly. This module provides an introduction to various modal and description logics, how to formalise knowledge and questions about this knowledge in these logics, different approaches to automated reasoning for these logics, and the relationship between these logics and first-order logic.

The module is entirely web-based, so a reliable internet connection is essential. Required Time per Week: 8-10 hours. A detailed module outline, learning outcomes, assessment information is available from the module website at http://www.cs.manchester.ac.uk/study/professional-development/study-options/. Registration deadline: 20 February 2015.

In the setting of secure multiparty computation, two or more parties with private inputs wish to compute some joint function of their inputs. The security requirements of such a computation are privacy (meaning that the parties learn the output and nothing more), correctness (meaning that the output is correctly distributed), independence of inputs, and more. This setting encompasses computations as simple as coin-tossing and agreement, and as complex as electronic voting, electronic auctions, electronic cash schemes, anonymous transactions, and private information retrieval schemes. Due to its generality, secure computation is a central tool in cryptography.

The aim of the school is to start from the basics, and teach the material needed to bring the participants up to date with the latest results in this exciting field. The school program includes approximately 27 hours of lectures and a half-day excursion to Jerusalem. The last day of the school will be a mini-workshop where latest results will be presented.

The target audience for the school is graduate students and postdocs in cryptography (we will assume that participants have taken at least one university-level course in cryptography). However, all faculty, undergrads and professionals with the necessary background are welcome. The winter school is open to participants from all over the world; all talks will be in English.

Participation is free, but registration is required. Please register by December 30, 2014. For more information, see http://crypto.2bwebsite.co.il/5th-biu-winter-school

There will be a Very Informal Gathering of Logicians at UCLA from 1:00 PM, Friday, January 30 to 1:00 PM, Sunday, February 1, 2015 (VIG 18), dedicated to Tony Martin on the occasion of his formal retirement. The invited speakers are Kit Fine, Sherwood Hachtman, Steve Jackson, Andrew Marks, Antonio Montalban (Hjorth lecturer), Itay Neeman, Charles Parsons, Pierre Simon, Sergei Starchenko, John Steel, Katrin Tent, Anush Tserunyan and Hugh Woodin.

There are no registration fees, and it is expected that travel grants will be available for graduate students and faculty in early career stages; write to ynm at math.ucla.edu if you are interested.
