| 摘要: |
| ω—语言是由有穷字母表∑上的某些无穷串组成的集合。被所谓的ω—有穷自动机接受的ω—语言称为ω—正则语言。在[4]中作者曾从集合的角度给出—ω—语言为ω—正则语言的几个充分条件。在本文作者仍从集合的角度给出一个ω—语言为ω—正则语言的充分条件,即若—ω—凸语言L满足L=adh(pref(L))=pref(L)tail(L),则L是—ω—正则语言。从而,确定了ω—正则语言类的一个子类。 |

| Abstract: |
| An ω-language is a set consisting of infinite-strings over some alphabet ∑, the ω-language accepted by some ω-finite state automation is called the ω-regular language.Several sufficient conditions for an ω-language is an ω-regular language are given by author from the point of view of the set in [4]. In this paper, author gives still from the point of view of the set a sufficient condition for an ω-language is an ω-regular language, i.e., if L is an ω-convex language, such that L=Adh(pref(L)) =Pref(L)Tail(L),then the L is an ω-regular language.Thus defined one subclass of the ω-regular languages class. |
