具有特殊跟踪时间的集合的拓扑熵

On the topological entropy of the set with a special shadowing time

Cao Zhao, Ercai Chen

摘要:

设$(X,d,T )$是一个具有规范性质的拓扑动力系统.对于$ α\in \mathbb R^+$和任何$x_0\in X$,定义$$ \mathbf D^{x_0}_α:=\Big\{x\in X: \lim\limits_{ε\to 0}\limsup\limits_{n\to\infty}\dfrac{\max\{t\in\mathbb N:~T^n(x)\in B_{t}( x_0,ε)\}}{n}\geq α\Big\}.$$然后我们有$h_{top}^{B} ( T, \mathbf D^{x_0}_α)= \dfrac{h_{top}(T)}{1+α} $,其中$h_{top}^{B} ( T, \mathbf D^{x_0}_α)$表示$\mathbf D^{x_0}_α.$的Bowen拓扑熵

英文摘要:

Let $(X,d,T )$ be a topological dynamical system with specification property. For $ α\in \mathbb R^+$ and any $x_0\in X$, define $$ \mathbf D^{x_0}_α:=\Big\{x\in X: \lim\limits_{ε\to 0}\limsup\limits_{n\to\infty}\dfrac{\max\{t\in\mathbb N:~T^n(x)\in B_{t}( x_0,ε)\}}{n}\geq α\Big\}.$$ Then we have $h_{top}^{B} ( T, \mathbf D^{x_0}_α)= \dfrac{h_{top}(T)}{1+α} $, where $h_{top}^{B} ( T, \mathbf D^{x_0}_α)$ denotes the Bowen topological entropy of $\mathbf D^{x_0}_α.$
