摘要：In this talk, we discuss continuous orbit equivalence (coe for short) between two continuous group actions on compact spaces. Roughly speaking, this means there exists a homeomorphism between the spaces which identifies orbits on two sides continuously. We survey some known results on coe rigid actions, i.e. actions for which coe between them and other actions implies they are topologically conjugate.
