关于超空间上诱导函数和群作用的几点注记

Some notes on induced functions and group actions on hyperspaces

Victor Donjuán, Natalia Jonard-Pérez, Ananda López-Poo

摘要:

讨论了拓扑空间之间的连续映射何时在它们各自的超空间之间导出连续函数的问题。在Fell超空间和Attouch-Wets超空间的情形下,刻画了诱导函数的连续性.此外,我们还研究了拓扑群$G$在拓扑空间$X$上的连续作用是否诱导出在$CL(X)$上的连续作用.

英文摘要:

We discuss the problem of when a continuous map between topological spaces induces a continuous function between their respective hyperspaces. We characterize the continuity of the induced function in the case of the Fell and Attouch-Wets hyperspaces. Additionally we explore the problem of whether a continuous action of a topological group $G$ on a topological space $X$ induces a continuous action on $CL(X)$.
