Title: A Pumping Lemma for Monotonous Super-Nets Languages
Authors: O. Gerstel. Z. Harpaz, R. Rinat
Abstract: A pumping lemma for languages recognized by a restricted type of Supef-nets is presented. This type of Super-nets, called monotonous, differs from the ussual Super-nets in the absence of restricting places, inhibiting arcs and lambda-transitions. The lemma can be used to prove languages to be uhrecognizable by monotonous Super-nets. An immediate corollary is the application of the lemma to other known types of Petri-nets. It is notable that the pumping lemma is very similar in structure to the one for regular languages.
