Around higher property (T)

Talk by Prof. Dr. Uri Bader

Speaker invited by: Prof. Dr. Alexander Gorodnik

Date: 23.05.22  Time: 14.05 - 15.05  Room: ETH HG G 43

For a finitely generated group, property (T) is equivalent to the vanishing of all first cohomology groups whose coefficient modules are unitary representations. In my talk I will discuss various analogue properties stemming from consideration of higher degree cohomologies. In particular, I will discuss vanishing results for lattices in semisimple groups. The talk will be based on a joint work with Roman Sauer.
