Matita is a new document-centric interactive theorem prover that integrates several Mathematical Knowledge Management tools and techniques.

Matita is traditional. Its logical foundation is the - Calculus of (Co)Inductive Constructions (CIC), and it can re-use - mathematical concepts produced by other proof assistants like - Coq and encoded in an - XML dialect. The interaction - paradigm of Matita is well known, having been inspired by - Proof General, and its +
