Experimenting Formal Proofs of Petri Nets Refinements
Petri nets are a formalism for modelling and validating critical systems. Generally, the approach to specification starts from an abstract view of the system under study. Once val...

Refinement Semantics and Loop Rules
Refinement semantics is an alternative to least fixpoint semantics that is more useful for programming. From it we derive a variety of rules for w h i l e-loops, for-loops, and loo...
