关于可扩群作用的性质

On Properties of Expansive Group Actions

Ali Barzanouni, Mahin Sadat Divandar, Ekta Shah

摘要:

研究了度量空间上可扩张群作用的若干性质,得到了子群的可扩张性与群作用的关系。通过反例论证了假设的必要性。我们还研究了覆盖映射的扩张性。进一步,我们定义了拓扑空间上群作用的轨道扩张度,并利用它来刻画扩张作用。

英文摘要:

We study several properties of expansive group actions on metric spaces and obtain relation between expansivity for subgroup and group actions. Through counter examples necessity of hypothesis are justified. We also study expansivity of covering maps. Further, we define orbit expansivity for group actions on topological spaces and use it to characterize expansive action.
