%0 Journal Article %T Distributional chaos in a sequence and topologically weak mixing for nonautonomous discrete dynamical systems %A Zhao, Yu %A Li, Risong %A Wang, Hongqing %A Liang, Haihua %J Journal of Mathematics and Computer Science %D 2020 %V 20 %N 1 %@ ISSN 2008-949X %F Zhao2020 %X Assume that \((W, g_{1,\infty})\) is a nonautonomous discrete dynamical system given by sequences \((g_{m})_{m=1}^{\infty}\) of continuous maps on the space \((W,d)\). In this paper, it is proven that if \(g_{1, \infty}\) is topologically weakly mixing and satisfies that \(g_{1}^{n}\circ g_{1}^{m}=g_{1}^{n+m}\) for any \(n,m\in\{0,1,\ldots\}\), then it is distributional chaos in a sequence. This result extends the existing one. %9 journal article %R 10.22436/jmcs.020.01.02 %U http://dx.doi.org/10.22436/jmcs.020.01.02 %P 14--20
