AI总结:

本文证明广义移位动力系统为稠密混沌当且仅当底映射无拟周期点,从而确立该类严格介于Devaney混沌与Li-Yorke混沌之间,并给出多种敏感性与混沌性质的等价刻画。

摘要:

在本文中,对于至少含两个元素的有限离散空间$X$、非空可数集$Γ$以及映射$φ:Γ\ oΓ$,我们证明广义移位动力系统$(X^Γ,σ_φ)$是稠密混沌的当且仅当$φ:Γ\ oΓ$没有任何(拟)周期点。因此,$X^Γ$上所有稠密混沌广义移位构成的类介于$X^Γ$上所有Devaney混沌广义移位构成的类与$X^Γ$上所有Li-Yorke混沌广义移位构成的类之间。此外,当$Γ$为无限可数集时,这些包含关系都是真包含。进一步,我们证明$(X^Γ,σ_φ)$是Li-Yorke敏感的(相应地,敏感的、强敏感的、渐近敏感的、syndetically敏感的、余有限敏感的、多重敏感的、遍历敏感的、时空混沌的、Li-Yorke混沌的)当且仅当$φ:Γ\ oΓ$至少有一个非拟周期点。

英文摘要:

In the following text, for finite discrete $X$ with at least two elements, nonempty countable $Γ$, and $φ:Γ\toΓ$ we prove the generalized shift dynamical system $(X^Γ,σ_φ)$ is densely chaotic if and only if $φ:Γ\toΓ$ does not have any (quasi-)periodic point. Hence the class of all densely chaotic generalized shifts on $X^Γ$ is intermediate between the class of all Devaney chaotic generalized shifts on $X^Γ$ and the class of all Li-Yorke chaotic generalized shifts on $X^Γ$. In addition, these inclusions are proper for infinite countable $Γ$. Moreover we prove $(X^Γ,σ_φ)$ is Li-Yorke sensitive (resp. sensitive, strongly sensitive, asymptotic sensitive, syndetically sensitive, cofinitely sensitive, multi-sensitive, ergodically sensitive, spatiotemporally chaotic, Li-Yorke chaotic) if and only if $φ:Γ\toΓ$ has at least one non-quasi-periodic point.
