区间马氏多重映射的熵共轭性

Entropy conjugacy for Markov multi-maps of the interval

James P. Kelly, Kevin McGoff

摘要:

本文考虑单位区间上的一类马尔可夫多重映射$\mathcal{F}$。任何多重映射都会产生一个轨迹空间,它是$[0,1]^{\mathbb{Z}_+}$的一个闭的、平移不变的子集。对于$\mathcal{F}$中的多重映射,我们证明了轨迹空间是与有限型移位共轭的(Borel)熵.此外,我们刻画了一组数字,可以得到的拓扑熵的多重映射在$\mathcal{F}$。

英文摘要:

We consider a class $\mathcal{F}$ of Markov multi-maps on the unit interval. Any multi-map gives rise to a space of trajectories, which is a closed, shift-invariant subset of $[0,1]^{\mathbb{Z}_+}$. For a multi-map in $\mathcal{F}$, we show that the space of trajectories is (Borel) entropy conjugate to an associated shift of finite type. Additionally, we characterize the set of numbers that can be obtained as the topological entropy of a multi-map in $\mathcal{F}$.
