$Δ$ -沿着整数序列集合的弱混合子集

$Δ$-weakly mixing subsets along a collection of sequences of integers

Jian Li, Kairan Liu

摘要:

本文对整数序列的集合提出了一个温和的条件,称为条件$(**)$,并证明了对于任何保测度系统,Pinsker $σ$ -代数是沿满足条件$(**)$的集合的平均的特征$σ$ -代数.我们引入了$Δ$ -弱混合子集的概念,并证明了正拓扑熵意味着存在$Δ$ -弱混合子集的集合的“好”序列。结果表明,正的拓扑熵蕴涵着沿移位素数多项式倍的多变量Li-Yorke混沌.

英文摘要:

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.
