Center node: "decision problems for petri nets with names"
  Abstract: AbstractWe prove several decidability and undecidability results for ν-PN, an exten-sion of P/T nets with pure name creation and name management. We give asimple proof of undecidability of reachability, by reducing reachability in netswith inhibitor arcs to it. Thus, the expressive power of ν-PN strictly surpassesthat of P/T nets. We prove that ν-PN are Well Structured Transition Sys-tems. In particular, we obtain decidability of coverability and termination, sothat the expressive power of Turing machines is not reached. Moreover, theyare strictly Well Structured, so that the boundedness problem is also decidable.We consider two properties, width-boundedness and depth-boundedness, thatfactorize boundedness. Width-boundedness has already been proved to be de-cidable. We prove here undecidability of depth-boundedness. Finally, we obtainAckermann-hardness results for all our decidable decision problems.Keywords: Petri nets, pure names, Well Structured Transition Systems,decidability1. IntroductionPure names are identiﬁers with no relation between them other than equal-ity [14]. Dynamic name generation has been thoroughly studied, mainly in theﬁeld of security and mobility [14] because they can be used to represent chan-nels, as in π-calculus [24], ciphering keys, as in spi-Calculus [2] or computingboundaries, as in the Ambient Calculus [4].In previous works we have studied a very simple extension of P/T nets [6],that we called ν-PN [25, 28], for name creation and management.
