摘要
用（G，X）表示一个群G作用在集合X上，并用F（g）表示被群G的元素g所稳定的点集．本文得到了关于数■F（g）|n的两个结果，并得到了这个数的几何意义．在某种意义上讲，它们是Burnside引理的推广．
Let (G,X) denote a group G acting on a set X, and let F(g) denote the set of all fixed points of g∈G. In thik note, we get two theorems about the mumber ■|F(g) |n and its geometric interpretation.
