论文摘要
在本文中,我们提出了一种温和的条件,称为条件$(**)$,用于整数序列,并表明,对于任何度量保存系统,Pinsker $σ$ -Algebra是一个特征性的$σ$ -SALGEBRA,沿着集合条件$(**)$(**)$(****)$。我们介绍了$δ$ - 伴有整数序列的混合子集的概念,并表明积极的拓扑熵意味着存在$δ$ - 伴随“良好”序列的集合。结果,我们表明阳性拓扑熵意味着沿移位质数的多项式时代的多变体Li-Yorke混乱。
In this paper, we propose a mild condition, named Condition $(**)$, for collections of sequence of integers and show that for any measure preserving system the Pinsker $σ$-algebra is a characteristic $σ$-algebra for the averages along a collection satisfying Condition $(**)$. We introduce the notion of $Δ$-weakly mixing subsets along a collection of sequences of integers and show that positive topological entropy implies the existence of $Δ$-weakly mixing subsets along a collection of "good" sequences. As a consequence, we show that positive topological entropy implies multi-variant Li-Yorke chaos along polynomial times of the shift prime numbers.
