摘要
考察了非本原代换及其诱导的集值映射的动力学性质.给出了该类代换诱导的超空间系统是Li-Yorke混沌的一个充分条件.证明了这类代换的拓扑熵为0,并且给出了这类代换诱导的集值映射具有零拓扑熵的一个充分条件.
As an important component of nonlinear science, the research on dynamical system has penetrated into many problems of agricultural production, such as prediction of corn yield and research on ecological difference equation. In this paper, we investigated dynamical properties for non-primitive substitution and the set-valued maps induced by the substitution. We gave a sufficient condition for the set-valued maps to be Li-Yorke chaotic, proved that the topological entropy of the substitution is zero, and gave a sufficient condition for the set-valued maps to have 0 topological entropy.
