Clinton Conley: Borel marker sets and hyperfiniteness

[this talk is a warmup for the Appalachian set theory workshop at CMU on October 24, where Su Gao (UNT) will speak on “Countable abelian group actions”] Mathematical logic seminar – September 29, 2015 Time:     12:30 – 13:30 Room:     Wean Hall 7201 Speaker:         Clinton Conley Department of Mathematical Sciences CMU Title:     Borel marker sets and hyperfiniteness Abstract:     A classical tool in ergodic theory is the Rokhlin lemma, which more or less states that any ergodic measure-preserving automorphism of a standard probability space is the uniform limit of periodic automorphisms. continue reading…
