非等距群作用的基本区域

摘要
我们将关于度量空间上等距群作用及其基本区域的结果推广到仅为连续群作用的情形。特别地,我们获得了一些结果,可得出紧群作用的基本区域的相对紧性。作为推论,我们获得了半黎曼相似变换的紧循环群为非本质的一个判据。

备注
In v2 the notion of a `strongly locally finite region' in Definition 2.1 replaces the notion of a `finitely self adjacent fundamental region' from v1. As a result, v2 is completely rewritten. See Remark 2.3 for further explanation
