摘要:

通过在紧致系统中引入强非游荡集的概念, 给出了系统为分布混沌的一个必要条件, 并构造了没有分布混沌对的LiYorke混沌子移位. 结果表明, 对于子移位分布混沌与LiYorke混沌不等价.

关键词: 强非游荡集, LiYorke混沌, 分布混沌, 子移位

Abstract:

The notion of  strongly nonwandering set is introduced into a compact system, by means of which a necessary condition is given for a system to be distributively chaotic and a LiYorke chaotic subshift without distributively chaotic pairs is constructed, which shows that subshift distributional chaos is not equivalent to LiYorke chaos.

Key words: strongly nonwandering set, LiYorke chaos, distributional chaos; subshift
