The Pumping Lemma for Regular Languages ... Learning the Pumping Lemma ... In order to learn how to apply the pumping lemma for regular languages to prove that some particular language is not regular, students must first have a firm understanding of the pumping lemma itself.

The pumping lemma for the regular languages formalizes this argument. 5.2 Pumping lemma. Consider a regular language L. Then L is accepted by some finite automaton M . Let p be the number of states of M . Now consider a word in L with at least p letters.

This page is an attempt to reconstruct some well-meaning but flawed pumping lemma proofs from a problem set I graded in spring 2006. ... Suppose that the set of palindromes were regular. Let n be the value from the pumping lemma. Consider the string w = 0n110n. w is clearly a palindrome and |w|>= n. By the pumping...

Any regular language L has a magic number p; And any long-enough word in L has the following property: Amongst its first p symbols is a segment you can find; Whose repetition or omission leaves x ... So there is a pumping lemma for all languages context-free, Although we do not have the same for those that are r.e.

Once again, proved with the assistance of the pumping lemma (and a little help from the closure properties). I guess that's why this problem was "starred". Sorry for trying to do it on-the-fly during a review!

Review of Basics of Proofs. The Pumping Lemma is generally used to prove a language is not regular. If a DFA, NFA or NFA-epsilon machine can be constructed to exactly accept a language, then the language is a Regular Language.
