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). It can re-use
+ mathematical concepts produced by other proof assistants (e.g.
+ Coq) when encoded in an
+ XML representation of CIC. The
+ interaction paradigm of Matita is familiar, being inspired by CtCoq and
+ Proof General. Its
+ proof language is procedural in the same spirit of LCF.
Matita is innovative:
+
+
+
+
+ 
+
+
+ 
+
+
+ the user interface sports high quality bidimensional rendering of
+ proofs and formulae transformed on-the-fly to MathML markup, on which direct
+ manipulation of the underlying CIC terms is still possible;
+
+
+
+ 
+
+
+ 
+
+
+
+ the knowledge base is distributed: every authored concepts can be
+ published becoming part of the Matita library which can be browsed as an hypertext
+ (locally or on the World Wide Web) and searched by means of
+ content-based queries;
+
+
+ 
+
+
+ the tactical language, part of the proof language, has
+ step-by-step semantics, enabling inspection and replaying of deeply
+ structured proof scripts.
