Up to the present we have not seriously limited the type of complex envisaged, that is the nature of the polyhedron II. The class of particular interest for the application to networks, and indeed the most noteworthy class from any viewpoint is the class of surfaces.

transitive, concurrency relation. By applying known techniques in lattice theory, from any such relation one can derive a closure operator, and then an orthocomplemented lattice. We prove that, for a general class of occurrence nets, those lattices, formed by closed subsets of net elements, are orth

Laura E. White M.D.,Heitham T. Hassoun M.D., FACSlanguage theory for Petri nets one considers completely sequentialized versions of Petri nets only. That is one assumes that a Petri net has one central run place which allows only a single transition to fire at a time; any sequence of such firings is called a firing sequence and the language of a P

Javairiah Fatima,Gustavo S. Oderich M.D., FACSrt introduction into systems biology we demonstrate how to develop and validate qualitative models of biological pathways in a systematic manner using the well-established Petri net analysis technique of place and transition invariants. We discuss special properties, which are characteristic ones fo
