On distributional chaos in non-autonomous discrete systems (1801.04445v1)
Published 13 Jan 2018 in math.DS
Abstract: This paper studies distributional chaos in non-autonomous discrete systems generated by given sequences of maps in metric spaces. In the case that the metric space is compact, it is shown that a system is Li-Yorke{\delta}-chaotic if and only if it is distributionally{\delta}'-chaotic in a sequence; and three criteria of distributional {\delta}-chaos are established, which are caused by topologically weak mixing, asymptotic average shadowing property, and some expanding condition, respectively, where {\delta} and {\delta}' are positive constants. In a general case, a criterion of distributional chaos in a sequence induced by a Xiong chaotic set is established.
