Recursive Petri nets (RPNs) have been introduced to model systems with dynamic structure. Whereas this model is a strict extension of Petri nets and contextfree grammars (w.r.t. the language criterion), reachability in RPNs remains decidable. However the kind of model checking which is decidable for Petri nets becomes undecidable for RPNs. In this work, we introduce a submodel of RPNs called sequential recursive Petri nets (SRPNs) and we study the model checking of the action-based linear time
more &raquo; ... ogic on SRPNs. We prove that it is decidable for all its variants : finite sequences, finite maximal sequences, infinite sequences and divergent sequences. At the end, we analyze language aspects proving that the SRPN languages still strictly include the union of Petri nets and context-free languages and that the family of languages of SRPNs is closed under intersection with regular languages (unlike the one of RPNs).
