two interesting references:

	Petri Nets are Monoids
     by  Jose Meseguer and Ugo Montanari
         SRI, Menlo Park CA 94025 USA     (and they are famous enough :-))
  

        From Petri Nets to Linear Logic
     by  Narciso Marti-Oliet and Jose Meseguer
        SRI and CSLI Stanford, CA 94305
