圆周上逆极限可扩的连续自映射

Continuous Self-maps with Expansive Inverse Limits on a Circle

本文研究了圆周上一类自映射ｆ的正向可扩性与其道极限的可扩性间的联系，得出圆周上的连续满射ｆ的逆极限可扩等价于ｆ拓扑共轭于扩张映射．

In this paper, we study the relationship between the positive expansiveness of a kind of self-maps on a circle and the expansiveness of their inverse limits, and obtain that, for every surjective continuous map f,the inverse limit of f is expansive if and only if f is topologically conjugate to an expanding map.
