Fixpoint Alternation and the Game Quantifier

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract / Description of output

Drawing on an analogy with temporal fixpoint logic, we relate the arithmetic fixpoint definable sets to the winning positions of certain games, namely games whose winning conditions lie in the difference hierarchy over ∑20. This both provides a simple characterization of the fixpoint hierarchy, and refines existing results on the power of the game quantifier in descriptive set theory.
