Title: Subspace arrangements and property T

Abstract: I will mainly talk about (my viewpoint at) a method for
proving property T started by Dymara and Januszkiewicz. Their original
motivation came from groups acting on dimensional buildings, but the
refined idea does not use anything more than angles between subspaces
in an finite dimensional Euclidian space. Parts of the talk are based
on a work of M. Ershov and A. Jaikin.
