In this paper,we construct a class of model-shift map τ1,and prove that the model-shift map is topological semi-conjugate with the usual shift map σ in symbol space,thus showing that it is Li-Yorke chaotic and non-Devaney Devaney chaotic,and also it describe the Sierpinski pad.
本文构造了一类拟移位映射τ1,并证明了此移位映射与符号空间上通常的移位映射σ拓扑半共轭,进而证明了τ1是Li—Yorke混沌非Devaney意义混沌的结论,并且用τ1描述了Sierpinski(谢尔宾斯基)垫。
According to the iterative orbit the shelf-map of the same topologically conjugate class topological properties, we discuss a class of shelf-map on compact spaces and it is proved that if there exits a topological semi-conjugate which is from compact spaces to symbolic spaces, then it has a minimal sub-system which displays Wiggins chaos and Martelli chaos.
证明了若该映射拓扑半共轭于符号空间上的转移自映射,则该映射存在Wiggins混沌和Martelli混沌的极小子系统。
