                    TYPES Summer School 2005

        Proofs of Programs and Formalisation of Mathematics

              August 15-26 2005, Goteborg, Sweden


During the last ten years major achievements have been made in using
computers for interactive proof developments to produce secure
software and to show interesting mathematical results. Recent major
results are, for instance, the complete formalisation of a proof of
the four colour theorem, and a formalisation of the prime number

This two weeks' course is for postgraduate students, researchers and
industrials who want to learn about interactive proof development.
The present school follows the format of previous TYPES summer school
(in Baastad 1993, Giens 1999, Giens 2002).  There will be introductory
and advanced lectures on lambda calculus, type theory, logical
frameworks, program extraction, and other topics with relevant
theoretical background.  Several talks will be devoted to

During these two weeks we will present three proof assistants: Coq,
Isabelle and Agda, which are state-of-the-art interactive theorem
provers.  Participants will get extensive opportunities to use the
systems for developing their own proofs. No previous knowledge of
type theory and lambda calculus is required.

The school is organised by the TYPES working group "Types for Proofs
and Programs", which is a project in the IST (Information Society
Technologies) program of the European Union. A limited number of grants
covering part of travel, fees and ackommodation are available. Neither
participation nor grants are restricted to TYPES participants.
