UK Virtual Operator Algebras Seminar: Expanders and generalisations

Ana Khukhro (University of Cambridge)

Thursday 4th June, 2020 16:00-16:45 Contact for Zoom info


After recalling some motivation for studying highly-connected graphs in the context of operator algebras and large-scale geometry, we will introduce the notion of "asymptotic expansion" recently defined by Li, Nowak, Spakula and Zhang. We will explore some applications of this definition, hopefully culminating in joint work with Li, Vigolo and Zhang.
