On Modal mu-Calculus with Explicit Interpolants
Giovanna D'Agostino, Giacomo Lenzi

Abstract:
This paper deals with the logic obtained by extending Kozen
mu-calculus with the so-called `` bisimulation quantifiers''.  These
quantifiers allow to look for a subset P satisfying a priperty F(P)
not only within the model, but also in any other model which is
bisimilar to the given one.  By using these quantifiers one can
describe explicitly the uniform interpolant of any formula of the
mu-calculus. In this work we provide a complete calculus for the
extended logic.
