MPRI M1 Course:
Interactive Theorem Proving and Applications
("Introduction aux assistants de preuve")

Objective: Interactive Theorem Proving is a technology of growing importance in computer science and mathematics. It is based on powerful logical languages with a strong expressivity and implementations allowing to establish a high degree of confidence in the correctness of the results. Among the applications, the mechanically checked proof of the Feit-Thomson theorem can be noted, as well as a correctness proof of the seL4 system, a secured operating system micro-kernel in the L4 tradition.

This course is an introduction into the fundamentals of interactive proof environments and will be practically illustrated with the Isabelle/HOL system. The examples will address problems of modelling and proof and will introduce into the techniques to proof properties of languages or systems. It gives also an introduction into some of the foundations of mathematics and computer science.

Goal: Getting practical experience for modeling and proving with interactive theorem proving environments. Units will usually take place at Bat. 640,14:00 - 17:30, room E105. They consist of a course and a following TP. At the end of the course, a small project will be developped individually which will become the grade for CC, which counts 40 percent.
