Groups acting on trees: representation theory and operator algebras

Presented by: 
Sven Raum EPFL - Ecole Polytechnique Fédérale de Lausanne
Tuesday 20th June 2017 - 13:30 to 14:30
INI Seminar Room 2
This talk summarises different aspects of my work on totally disconnected groups, their representation theory and their operator algebras.  Our guiding examples are non-discrete groups acting on trees.  I will address simplicity, amenability and classification of operator algebras associated with groups acting on trees as well as representation theoretic aspects such as the admissibility conjecture.
