On Almost Representations of Property (T) Groups

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/135836Property (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.10 pages, minor changes, references addedOperator AlgebrasGroup Theory47C99, 20E99On Almost Representations of Property (T) Groupstext
