### Dedukti

Dedukti is a proof-checker for the $\lambda \Pi$-calculus modulo. As it can be parametrized by an arbitrary set of rewrite rules, defining an equivalence relation, this calculus can express many different theories. Dedukti has been created for this purpose: to allow the interoperability of different theories.

Dedukti's core is based on the standard algorithm [42] for type-checking semi-full pure type systems and implements a state-of-the-art reduction machine inspired from Matita's [40] and modified to deal with rewrite rules.

Dedukti's input language features term declarations and definitions (opaque or not) and rewrite rule definitions. A basic module system allows the user to organize its project in different files and compile them separately.

Dedukti has been developed by Mathieu Boespflug, Olivier Hermant, Quentin Carbonneaux, and Ronan Saillard. It is composed of about 1000 lines of OCaml.
