Lowness for the Class of Random Sets
Antonín Kucera, Sebastiaan A. Terwijn

Abstract:
A positive answer to a question of M. van Lambalgen and D. Zambella 
whether there exist nonrecursive sets that are low for the class of 
random sets is obtained. Here a set A is low for the class RAND of 
random sets if RAND = RAND^A.
