摘 要:
首先研究了Bowen拓扑熵中张成集与分离集的有关性质.设(x,f)是一个紧致拓扑动力系统,得到了(1)f∈C^0(X,X)必有有限的(n,ε)-张成集;(2)f的每一个(n+1,ε)-张成集必是(n,ε)一张成集;(3)f的每一个(n,ε)-分离集都是(n+1,ε)-分离集;(4)f的每一个(n,ε)-分离集都是有限集;最后讨论了在一致收敛下张成集和分离集的一个性质.[著者文摘]

Abstract:
This paper first discusses the spanning sets and separating sets in Bowen-topological entropy, and obtains some characters about them : ( 1 ) f ∈ (X,X) has 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. Finally, it discusses a character about the spanning set and separating set under the uniformly convergence.[著者文摘]
