derivatives of regular expressions, was proposed by Brzozowski [4]. Among the well-known con- structions of ϵ-free non-deterministic finite automata (NFA), the . Abstract: Brzozowski’s derivatives of a regular expression are developed for constructing deterministic automata from the given regular expression in the. In this paper,some lemmas of the regular expressions are discussed Also the generalizations of the Brzozowski derivatives are proved as.

Given a finite alphabet A of symbols, [2] a generalized regular expression denotes a possibly infinite set of finite-length strings of symbols from A. Considering all the derivatives of a fixed generalized regular expression R results in only finitely many different languages.
