Abstract

This paper proposes a method to factorise the verification of temporal properties for multi-threaded programs over groups of different threads. Essentially, the method boils down to showing that there exists a group of threads that establishes the property of interest, while the remaining threads do not affect it. We fine-tune the method by identifying for each property particular conditions under which the preservation is necessary. As a specification language we use the so-called specification patterns developed as part of the Bandera project at Kansas State University. For each specification pattern we propose a decomposition rule. We have shown the soundness of each rule using the pattern mappings as defined for LTL. The proofs have been formalised using the theorem prover Isabelle.
