We study the notion of class refinement in a concurrent object-oriented setting. Our model is based on a combination of action systems and classes. An action system describes the b...
Inspired by the properties of the refinement development of the Mondex Electronic Purse, we view an atomic action as a family of transitions with a common before-state, and differ...
We automatically verify Back's atomicity refinement law and a classical data refinement law for action systems. Our novel approach mechanises a refinement calculus based on K...
Inspired by the properties of the refinement development of the Mondex Electronic Purse, we view an isolated atomic action as a family of transitions with a common before-state, an...
: This paper gives a definition of ASM refinement suitable for the verification that a protocol implements atomic transactions. We used this definition as the basis of the formal v...
