Spanning Set and Separating Set, the Bowen-Topological Entropy in the Product System;
张成集和分离集，积系统的Bowen拓扑熵
This paper first discusses the spanning sets and separating sets in Bowen-topological entropy,and obtains some characters about them:(1)f∈X,Xhas certainly limited(n,ε)-spanning set;(2) Every(n+1,ε)-spanning set is the(n,ε)-spanning set;(3) Every(n,ε)-separating set is the(n+1,ε)-separating set;(4)Every(n,ε)-separating set is a limited set.
首先研究了Bowen拓扑熵中张成集与分离集的有关性质。
