Around higher property (T)

Vortrag von Prof. Dr. Uri Bader

Sprecher eingeladen von: Prof. Dr. Alexander Gorodnik

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.
