TLA+ Proofs

Abstract : TLA+ is a specification language based on standard set theory and temporal logic that has constructs for hierarchical proofs. We describe how to write TLA+ proofs and check them with TLAPS, the TLA+ Proof System. We use Peterson's mutual exclusion algorithm as a simple example and show how TLAPS and the Toolbox (an IDE for TLA+) help users to manage large, complex proofs. A shorter version of this article was published at the conference Formal Methods 2012.
