In this work, we look at the extension of classical discrete dynamical system to multidimensional discrete-time dynamical system by characterizing chaos notions on \({\mathbb {Z}}^d\)-action. The \({\mathbb {Z}}^d\)-action on a space X has been defined in a very general manner, and therefore we introduce a \({\mathbb {Z}}^d\)-action on X which is induced by a continuous map, \(f:{\mathbb {Z}}\times X \rightarrow X\) and denotes it as \(T_f:{\mathbb {Z}}^d \times X \rightarrow X\). Basically, we wish to relate the behavior of origin discrete dynamical systems (Xf) and its induced multidimensional discrete-time \((X,T_f)\). The chaotic behaviors that we emphasized are the transitivity and dense periodicity property. Analogues to these chaos notions, we consider k-type transitivity and k-type dense periodicity property in the multidimensional discrete-time dynamical system. In the process, we obtain some conditions on \((X,T_f)\) under which the chaotic behavior of \((X,T_f)\) is inherited from the original dynamical system (Xf). The conditions varies whenever f is open, totally transitive or mixing. Some examples are given to illustrate these conditions.

多维离散时间动力系统混沌行为的充分条件

在这项工作中,我们通过刻画\({\ mathbb {Z}} ^ d \)作用上的混沌概念,研究了经典离散动力系统到多维离散时间动力系统的扩展。在空间X上的\({\ mathbb {Z}} ^ d \) -动作已以非常一般的方式定义,因此我们在...上引入了\({\ mathbb {Z}} ^ d \) -action由连续映射\(f:{\ mathbb {Z}} \ times X \ rightarrow X \)诱导的X,并表示为\(T_f:{\ mathbb {Z}} ^ d \ times X \ rightarrow X \)。基本上,我们希望将原始离散动力系统的行为(X,  f)及其诱导的多维离散时间\((X,T_f)\)。我们强调的混沌行为是传递性和密集周期性。类似于这些混沌概念,我们考虑了多维离散时间动力系统中的k型传递性和k型密集周期性。在这个过程中,我们得到在某些条件\((X,T_f)\)在其下的混沌行为\((X,T_f)\)是从原始动力系统(继承X,  ˚F)。每当f打开,完全传递或混合时,条件都会变化。给出了一些例子来说明这些情况。
