The axiom of real Blackwell determinacy

Research output: Contribution to journalArticlepeer-review


The theory of infinite games with slightly imperfect information has been developed for games with finitely and countably many moves. In this paper, we shift the discussion to games with uncountably many possible moves, introducing the axiom of real Blackwell determinacy Bl-AD (as an analogue of the axiom of real determinacy AD ). We prove that the consistency strength of Bl-AD is strictly greater than that of AD.
