On Almost Representations of Property (T) Groups

Vladimir Manuilov, Chao You

Published 2007-08-09, updated 2007-08-12Version 2

Property (T) for groups means a dichotomy: a representation either has an invariant vector or all vectors are far from being invariant. We show that, under a stronger condition of A.Zuk, a similar dichotomy holds for almost representations as well.
