摘要

让 G 是一个无限可数离散可亲群。对于紧凑度量空间X上的任意G作用,证明了对于由G的非空有限子集组成的任意序列\((G_n)_{n\rightarrow \infty }|G_n|=\infty \),平斯克(Pinsker)(\sigma \)代数是\((G_n)_{n\ge 1}\)的特征因子。因此,对于一类 G 拓扑动力系统,正拓扑熵意味着沿着一类由 G 的非空有限子集组成的序列的平均李-约克混沌。

Pinsker $$\sigma $$ -Algebra Character and Mean Li–Yorke Chaos

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 \(\lim _{n\rightarrow \infty }|G_n|=\infty \), Pinsker \(\sigma \)-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.
