Hua Shao, Guanrong Chen, Yuming Shi

摘要:

本文建立了诱导非自治集值系统与有限型子移位之间的拓扑(等)共轭和(等)对偶。首先,给出了非自治离散系统与有限型子移位拓扑共轭的充要条件。进一步得到了它与有限型子移位拓扑等共轭或等共轭的几个充分条件。在此基础上,给出了序列的拓扑熵估计和Li-Yorke混沌和分布混沌的几个判据。其次,研究了非自治离散系统与其诱导集值系统之间的若干相关动力学行为之间的关系。在此基础上,进一步建立了诱导集值系统与有限型子移位之间的拓扑(等)共轭和(等)对偶。从而得到了诱导集值系统的拓扑熵的估计,并建立了序列中Li-Yorke混沌和分布混沌的几个判据.其中一些结果不仅将已有的自治离散系统的相关结果推广到非自治离散系统,而且放宽了文献中相应结果的假设条件.最后给出了两个例子。

英文摘要:

This paper establishes topological (equi-)semiconjugacy and (equi-)conjugacy between induced non-autonomous set-valued systems and subshifts of finite type. First, some necessary and sufficient conditions are given for a non-autonomous discrete system to be topologically semiconjugate or conjugate to a subshift of finite type. Further, several sufficient conditions for it to be topologically equi-semiconjugate or equi-conjugate to a subshift of finite type are obtained. Consequently, estimations of topological entropy and several criteria of Li-Yorke chaos and distributional chaos in a sequence are derived. Second, the relationships of several related dynamical behaviors between the non-autonomous discrete system and its induced set-valued system are investigated. Based on these results, the paper furthermore establishes the topological (equi-)semiconjugacy and (equi-)conjugacy between induced set-valued systems and subshifts of finite type. Consequently, estimations of the topological entropy for the induced set-valued system are obtained, and several criteria of Li-Yorke chaos and distributional chaos in a sequence are established. Some of these results not only extend the existing related results for autonomous discrete systems to non-autonomous discrete systems, but also relax the assumptions of the counterparts in the literature. Two examples are finally provided for illustration.
