Abstract

Axioms for domain operations in several variants of Kleene algebras and their semiring reducts are presented. They provide abstract enabledness conditions for algebras designed for the verification and refinement of action systems, probabilistic protocols, basic processes and games. The axiomatisations are simpler, more uniform and more flexible than previous attempts; they are especially suited for automated deduction. This is further demonstrated through the automated verification of some classical refinement laws for action systems.
