Abstract: Abstract interpretation is a paradigm that has been successfully used in the verification and optimization of programs. This paper presents a new approach for the analysis of Petri Nets based on abstract interpretation. The main contribution is the capability of deriving non-structural invariants that can increase the accuracy of structural methods in calculating approximations of the reachability space. This new approach is illustrated with the verification of two examples from the literature.
