局部紧群和Property A(英文)

Locally Compact Groups and Property A

本文证明了对于具有左不变Haar测度的σ-紧局部紧群,如果存在一个在某个紧空间上的amenable群作用,则这个群具有Property A.

In this note, we prove that for σ-compact locally compact group with left invari- ant Haar measure, the existence of amenable action on some compact space implies Property A.
