Coq

Theorem prover based on lambda-C

Developed in the LogiCal project, the Coq tool is a formal proof management system a proof done with Coq is mechanically checked by the machine.

In particular, Coq allows

• the definition of functions or predicates,
• to state mathematical theorems and software specifications,
• to develop interactively formal proofs of these theorems,
• to check these proofs by a small certification “kernel”.

Coq is based on a logical framework called “Calculus of Inductive Constructions” extended by a modular development system for theories.

CoqIde is installed if the x11-toolkits/ocaml-lablgtk2 port is installed.
