Abstract

I will introduce a construction by Balcar and Franek of the Boolean algebra of clopen sets of the universal minimal dynamical system for discrete groups. I will show how that generalizes to topological groups. I will talk about a couple of applications of this approach, e.g. to groups of automorphisms of uncountable structures using methods of Kechris, Pestov and Todorcevic connecting structural Ramsey theory and topological dynamics.

We will have lunch and dinner with the speaker, please email lynn@math.uic.edu if you would like to join.
