Colloquium Series Seminar

Classification and rigidity for group von Neumann algebras
Tuesday, April 13, 2021
4:00-5:00 PM
Off Campus Location
Any countable group G gives rise to a von Neumann algebra L(G). The classification of these group von Neumann algebras is a central theme in operator algebras. I will survey recent rigidity results which provide instances when various algebraic properties of groups, such as the presence or absence of a direct product decomposition, are remembered by their von Neumann algebras. I will also explain the strongest such rigidity results, where L(G) completely remembers G, and discuss some of the open problems in the area.
