摘要

我们证明，对于可数无限离散群在紧凑可元空间上的每一个最小作用，如果不变 Borel 概率度量的单纯形的极边界是封闭的，并且具有有限的覆盖维度，那么该作用就具有小边界特性。

Bauer simplices and the small boundary property

We show that, for every minimal action of a countably infinite discrete group on a compact metrizable space, if the extreme boundary of the simplex of invariant Borel probability measures is closed and has finite covering dimension then the action has the small boundary property.
