Title:Applications of Slaman-Woodin coding
Seminar:Logic Seminar
Speaker:Keita Yokoyama, Tokyo Institute of Technology and Pennsylvania State University
Abstract:
In this talk, I will explain several applications of the coding theorem for Turing degrees by Slaman and Woodin, including Simpson's theorem which states that the theory of Turing degrees and the second-order theory of arithmetic are biinterpretable, and the theorem by Nerode and Shore which states that every automorphism of Turing degrees is the identity on a cone.
