Abstract

Regular languages are closed under union, intersection, complementation, Kleene-closure and reversal operations. Regular languages can be classified into infix-free, prefix- free and suffix-free. In this paper various closure properties of prefix-free regular languages are investigated and result shows that prefix-free regular languages are closed under union and concatenation. Under complementation, reverse, Kleene-closure and intersection operations prefix-free regular languages are not closed.
