Chunlin Liu, Rongzhong Xiao, Leiye Xu

AI总结:

本文证明了在无限可数离散顺从群作用下Pinsker $\sigma$-代数为特征因子,并由此推导出一类拓扑动力系统中正拓扑熵蕴含均值Li-Yorke混沌。

摘要:

设 $G$ 为无限可数离散顺从群。对于紧致度量空间 $X$ 上的任意 $G$-作用,证明了对任意由 $G$ 的非空有限子集构成且满足 $\lim_{n\to \infty}|G_n|=\infty$ 的序列 $(G_n)_{n\ge 1}$,Pinsker $\sigma$-代数是 $(G_n)_{n\ge 1}$ 的特征因子。由此可得,对于一类 $G$-拓扑动力系统,正拓扑熵意味着沿着一类由 $G$ 的非空有限子集构成的序列呈现均值 Li-Yorke 混沌。

英文摘要:

Let $G$ be an infinite countable discrete amenable group. For any $G$-action on a compact metric space $X$, it is proved that for any sequence $(G_n)_{n\ge 1}$ consisting of non-empty finite subsets of $G$ with $\lim_{n\to \infty}|G_n|=\infty$, Pinsker $σ$-algebra is a characteristic factor for $(G_n)_{n\ge 1}$. As a consequence, for a class of $G$-topological dynamical systems, positive topological entropy implies mean Li-Yorke chaos along a class of sequences consisting of non-empty finite subsets of $G$.
