Show a language is not regular by using the pumping lemma. 0. Pumping Lemma does not hold for the regular expression $101$, or similar? 3. WebExpert Answer. 1st step. All steps. Final answer. Step 1/5. Yes, there are pumping lemmas for languages beyond the regular languages, including the context-free and recursively enumerable languages. However, the pumping lemma for recursive languages is more complex than that for regular languages and context-free languages.

WebJul 6, 2024 · For regular languages, the Pumping Lemma gave us such a property. It turns out that there is a similar Pumping Lemma for context-free lan- guages. The proof of this lemma uses parse trees. In the proof, we will need a way of representing abstract parse trees, without showing all the details of the tree.

If the language were actually a b n Q ∗ b m, it would be regular. Hint: Note that the only way to eliminate B from a term is to replace it with c A.
