Abstract

It is proved that if \(G\) is a group and \(\pi\) is a pseudorepresentation of \(G\) in a Banach space \(E\) with a sufficiently small defect and if \(\pi\) is a sufficiently small perturbation of the identity representation of \(G\) in \(E\), then \(\pi(g)=1_E\) for all \(g\in G\).

群伪表示的一个新的平凡定理

摘要

证明如果\(G \)是一个组并且\(\ pi \)是Banach空间\(E \)中具有足够小的缺陷的\(G \)的伪表示,并且\\\\ pi \ )是的身份表示的足够小的扰动\(G \)\(E \) ,然后\(\ PI(克)= 1_E \)对所有\(克\ G中\)
