Groebner Basis Procedures for Testing Petri Nets
  This paper contains introductory material on Petri nets and Groebner basis theory and makes some observations on the relation between the two areas. The aim of the paper is to show how Groebner basis procedures can be applied to the problem of reachability in Petri nets, and to give details of an application to testing models of navigational systems.
