摘要:
本文定义并讨论了Z^d作用的任意子集的拓扑慢熵的维数概念。此外,本文还提出了Z^d作用量的测度论慢熵的概念,它是对Brin和Katok [2]的修正.本文研究了Bowen拓扑熵[3,17]与拓扑慢熵的关系,并给出了符号系统中拓扑慢熵的几个例子。具体地,证明了一个变分原理。
英文摘要:
This paper defines and discusses the dimension notion of topological slow entropy of any subset for Z^d actions. Also, the notion of measure-theoretic slow entropy for Z^d actions is presented, which is modified from Brin and Katok [2]. Relations between Bowen topological entropy [3,17] and topological slow entropy are studied in this paper, and several examples of the topological slow entropy in a symbolic system are given. Specifically, a variational principle is proved.
