Document 1.pdf (478 KB)


Abstract

We present a pumping lemma for the class of collapsible pushdown graphs of level 2. This pumping lemma even applies to epsilon-contractions of level 2 collapsible pushdown graphs. Our pumping lemma also improves the bounds of Hayashi's pumping lemma for indexed languages.
