[PDF] proving languages not regular using Pumping Lemma

The Pumping Lemma is used for proving that a language is not regular If L is a regular language, then there is an integer n > 0 with the property that: (*) for any string x ∈ L where x ≥ n, there are strings u, v, w such that (i) x = uvw, (ii) v = ǫ, (iii) uv ≤ n, (iv) uvkw ∈ L for all k ∈ N
