A class of languages is closed under a given operation if the resulting language belongs to this class whenever the operands belong to it. We examine the closure properties of various subclasses of regular languages under basic operations of intersection, union, concatenation and power, positive ...
摘要: This article is an investigation to the theory of ω-languages. The characterization of linear ω-languages by automaton and grammars is given. The closure properties by boolean and topological operations for such a family of ω-languages are studied.关键词:...

By the properties of an closure operator c and an involution i, in order to determine the orbit Oc,iX(A) of a set A it is sufficient to determine the sets A,c(A),i(c(A)),c(i(c(A))),i(c(i(c(A))),… and A,i(A),c(i(A)),i(c(i(A))),c(i(c(i(A))),… ....
