Groups and Dynamics Seminar

Measured equivalence relations and their full groups

Todor Tsankov of California Institute of Technology

I will give a brief overview of the theory of countable, measure-preserving equivalence relations and their connections with different branches of mathematics. Then I will explain how full groups can be used to differentiate equivalence relations and sketch some recent results in that direction. The talk is based on joint work with John Kittrell.
