Wednesday 13th July 2022: 16.00 – 17.00

We are delighted to welcome Professor Goulnara Arzhantseva, University of Vienna, to the University of Bristol to deliver a Heilbronn colloquium.

The colloquium with take place in Lecture theatre 2.41, Fry Building at 16:00 – 17:00 followed by a wine reception in the Fry Common Room. 

Title: Approximations of infinite groups

Abstract: We discuss various still open questions on approximations of finitely generated groups, focusing on finite-dimensional approximations such as residual finiteness and soficity. We survey our results on the existence and stability of metric approximations. We suggest a few conjectures, e.g. on Gromov hyperbolic groups and their infinite monster limits. The setting is rather general and the involved concepts are transversal to various areas of mathematics. 

Based on joint works with Liviu Paunescu (Bucharest).

 

The talks will be held in-person only. Spaces are limited in the room, so we ask that you please register via this form if you are intending to come in person. Once capacity is reached, we will close registration and any current remaining spaces will be allocated on a first come basis.
