Course description and aims

This course gives fundamental knowledge on concurrent computation using formal systems such as Milner's CCS (Calculus of communicating systems) and pi-calculus. The instructor explains several basic notions such as structural congruence and bi-simulation on the pi-calculus. Then, he proceeds to the pi-calculus, which is an extension of CCS by adding name-passing mechanism. The expressiveness of the pi-calculus is explained giving an translation of the lambda calculus and the one of an object-oriented programming language. These formal systems give us the foundation of reasoning of concurrency.
The aim of this course is for students to understand how to describe concurrent notions in the formal systems.
