Webb3 Undecidability Proofs via the Recursion Theorem Previously we have seen two techniques to prove that certain languages are undecidable: diagonalization and reduction.

Webb20 okt. 2014 · By the principle of transfinite recursion, there is a function s: A → V such that s ( b) = F ( s ↾ b) for every b ∈ A. In this case, it follows that s ( b) is the unique y such that φ ( a, b). Thus, since s is a set, it follows in ZC that ran ( s) is a set, and so we’ve got the image of A under φ as a set, which verifies replacement.

WebbClassical Computability Theory Classical computability theory is the theory of functions on the integers com-putable by a nite procedure. This includes computability on many count-able structures since they can be coded by integers. Computable functions include the recursive functions of G odel [1934], and the Turing machines Webbcan be supported in equilibrium. The standard theory o ers, at least in principle, a recipe for answering this question: rst, use the recursive analysis of Abreu, Pearce and Stacchetti (1990) (henceforth APS) to determine the worst possible equilibrium payo for each player (which may be strictly worse than just repeatedly playing a static Nash
