TITLE: Equilibria in Semantic Games SPEAKER: Pietro Galliani ABSTRACT: Game theoretic semantics for logics of imperfect information, given a model, associate every sentence to a (usually two-player) game; the sentence is said to be true if and only if one of the two players has a winning strategy. In this talk, I will review some recent generalizations of these semantics, introducing the corresponding notions of equilibrium and estabilishing some preliminary relations among them.
