Formalization of the pumping lemma for context-free languages (1510.04748v1)
Published 16 Oct 2015 in cs.FL
Abstract: Context-free languages (CFLs) are highly important in computer language processing technology as well as in formal language theory. The Pumping Lemma is a property that is valid for all context-free languages, and is used to show the existence of non context-free languages. This paper presents a formalization, using the Coq proof assistant, of the Pumping Lemma for context-free languages.
