Recent and upcoming talks by John Clemens
John Clemens: The recursion theorem in set theory
Tuesday, September 27 from 3 to 4pm
Room: MB 124
Speaker: John Clemens (BSU)
Title: The Recursion Theorem in Set Theory
Abstract: Kleene’s Recursion Theorem is a simple yet powerful result about computable functions, which asserts the existence of functions which “know their own code” in some suitably nice enumeration of the computable functions. continue reading…

Wednesday, September 16 from 3 to 4pm
Room: MP 207
Speaker: John Clemens (BSU)
Title: Isomorphism of homogeneous structures
Abstract: The theory of Borel reducibility of equivalence relations can be used to gauge the complexity of the isomorphism problem for a collection of countable structures. continue reading…

John Clemens: Treeable equivalence relations and descriptive complexity
Monday, May 14, 2012, 16.30
Speaker: John Clemens (University of Münster)
Title: Treeable equivalence relations and descriptive complexity
Abstract:
The property of treeability has been wellstudied in the context of countable Borel equivalence relations, but has been little studied up to now in the uncountable case. continue reading…
