Dear All, We are delighted to present the MaPSS Seminar topic of Monday 24/10; please see the abstract below. **This Semester the Seminar will always run on Monday, at 5:00pm in 535A** Following the talk, there will be pizza on offer. Speaker: Stephan Tornier (ETH Zurich) Title: On Property (T) and amenability Abstract: Both Property (T) and amenability, introduced by Kazhdan and von Neumann in 1967 and 1929 respectively, are properties of locally compact group. They are at the heart of rigidity theory of locally compact groups and their lattices, and have become vital in many other respects. This talk provides an introduction to these properties and their interplay along with basic examples, featuring Kazhdan’s original interest in Property (T): it implies finite generation of the fundamental groups of certain locally symmetric spaces. Supervisors, please encourage your students to attend. Thanks, MaPSS Organizers
