MaPSS: Mathematical Postgraduate Seminar Series: Stephan Tornier (ETH Zurich) -- On Property (T) and amenability

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
