Petri Net Semantics of the Finite pi-Calculus

摘要

In this paper we propose a translation into high level Petri nets of a finite fragment of the pi-calculus. Our construction renders in a compositional way the control flow aspects present in pi-calculus process expressions, by adapting the existing graph-theoretic net composition operators. Those aspects which are related to term rewriting, as well as name binding, are handled through special inscription of places, transitions and arcs, together with a suitable choice of the initial marking for a compositionally derived high level Petri net.
