For any splitting of s in x,y,z with the … WebbBy the pumping lemma xz L. However, there are fewer a’s at the beginning of the string than at the end of the string, so xz can’t be in L. There is no way to divide s into xyz so the pumping lemma holds. This means that the pumping lemma does not hold for L. Since the pumping lemma must hold for all regular languages, L must not be regular.

WebbPumping Lemma for Regular Languages and its Application Every regular Language can be accepted by a finite automaton, a recognizing device with a finite set of states and no auxiliary memory. This finiteness of the set is used by the pumping lemma in proving that a language is not regular.
