摘要:
本文给出了三种自由半群作用的动力系统的拓扑熵的定义,首先证明了这三种定义的等价性. 在此定义的基础上对拓扑熵性质进行了讨论. 主要包括以下结论:在等度拓扑共轭下拓扑熵的不变性以及这种拓扑熵的power rule性质.
Abstract:
In this paper,we define the entropy and preimage entropy of free semigroup actions in a new method. Based on these definitions,we get some relations between topological entropy and measure entropy,and the relations among kinds of preimage entropies. The main results of this paper are as follows:(1)The topological entropy is invariant under equi-conjugacy;(2)The power rule for the measure-theoretic entropy holds.
