Empowering the?Event-B Method Using External Theoriesway than usual Event-B events. We advocate that these WD conditions are sufficient to define transitions that preserve (inductive) invariants and safety properties, thus providing easier and reusable proof methods for model invariant preservation. We rely on the finite automata example to illustrate our approach.
