摘要:

令f表示由符号集{0,1}上非本原且非等长代换诱导的系统. 考虑f的拓扑熵及发生混沌性态的可能性, 证明了f的拓扑熵为零, 并给出了f不含分布混沌对的充分条件.

关键词: 代换系统, 混沌, 拓扑熵

Abstract:

Let f denote a system induced by a nonprimitive and nonconstantlength substitution over the alphabet {0,1}. We investigated the topological entropy of f and the possibilities for f to occur chaoticbehaviors and proved that the topological entropy of f is zero, and gave a sufficient condition for f to contain no distributively chaotic pairs.

Key words: substitution system, chaos, topological entropy
