The goal of Proof Central is to foster development, understanding, and application of proof methods, especially methods that are fundamental in computer science. Proof Central hosts Athena, both a programming language and an interactive theorem proving environment. Versions for Windows, Mac, and Linux are downloadable from this site. A User’s Guide and Reference Manual are provided, as are support tools such as an Emacs athena-mode to aid in preparation and editing of files containing Athena declarations, definitions, procedures, and proofs. Athena Version 1.4 was released on 19 December 2017.
Proof Central also hosts support materials for a new textbook for learning proof methods and practicing their application:
