可迁映射的函数空间的拓扑结构

The topological structure of function space of transitive maps

Zhaorong He, Jian Li, Zhongqiang Yang

摘要:

设$C(\mathbf I)$是${\mathbf I}=[0,1]$中所有具有一致收敛拓扑的连续自映射的集合.一个映射$f\in C({\mathbf I})$称为传递映射,如果对于$\mathbf{I}$中的每对非空开集$U,V$,存在一个正整数$n$使得$U\cap f^{-n}(V)\not=\emptyset.$我们记$T(\mathbf{I})$和$\overline{T(\mathbf{I})}$为空间$C(\mathbf I)$中所有传递映射及其闭包的集合.本文证明了$T(\mathbf{I})$和$\overline{T(\mathbf{I})}$同胚于可分Hilbert空间$\ell_2$ .

英文摘要:

Let $C(\mathbf I)$ be the set of all continuous self-maps from ${\mathbf I}=[0,1]$ with the topology of uniformly convergence. A map $f\in C({\mathbf I})$ is called a transitive map if for every pair of non-empty open sets $U,V$ in $\mathbf{I}$, there exists a positive integer $n$ such that $U\cap f^{-n}(V)\not=\emptyset.$ We note $T(\mathbf{I})$ and $\overline{T(\mathbf{I})}$ to be the sets of all transitive maps and its closure in the space $C(\mathbf I)$. In this paper, we show that $T(\mathbf{I})$ and $\overline{T(\mathbf{I})}$ are homeomorphic to the separable Hilbert space $\ell_2$.
