Graphical VERSUS logical specifications
Résumé
This paper studies the relations between two specification formalisms and verification methods for concurrent systems, namely Larsen-Thomsen's modal transition systems - here called graphical specifications - and Hennessy-Milner logic. We show that any graphical specification may be expressed by a logical specification having the same models. Conversely, we give a characterization of the formulate that are graphically representable.
