Amenable dynamical systems over locally compact groups
February 21, 2020 1pm, 646 PGH
Abstract
This talk will start with a description of amenability for locally compact groups and the notions of topological amenability and Zimmer amenability for locally compact group actions. The main new results discussed will be a Reiter-type characterization of Zimmer amenability, a characterization of topological amenability in terms of Zimmer amenability of a second dual action, and (if time permits) further operator algebraic characterizations of these in terms of module versions of the weak expectation property and injectivity.
