Program Composition in Isabelle/UNITY
We describe the mechanization of recent examples of compositional reasoning, due to Charpentier and Chandy [4]. The examples illustrate a new theory for composition proposed by Ch...

Reasoning About Synchronic Groups
Swarm is a computational model which extends the UNITY model in three important ways: (1) UNITY’s fixed set of variables is replaced by an unbounded set of tuples which are add...

We show that the traditional notion of superposition as used for supporting parallel program design can subsume both composition and refinement relationships when non-deterministi...

Mechanical Verification of a Garbage Collector
Abstract. We describe how the PVS verification system has been used to verify a safety property of a garbage collection algorithm, originally suggested by Ben-Ari. The safety prope...
