Das Seminar basiert auf dem Buch Communicating and Mobile Systems: the Pi-Calculus von Robin Milner.
Communication is a fundamental and integral part of computing, whether between different computers on a network, or between components within a single computer. In this book Robin Milner introduces a new way of modelling communication that reflects its position. He treats computers and their programs as themselves built from communicating parts, rather than adding communication as an extra level of activity. Everything is introduced by means of examples, such as mobile phones, job schedulers, vending machines, data structures, and the objects of object-oriented programming. But the aim of the book is to develop a theory, the pi-calculus, in which these things can be treated rigorously.
The pi-calculus differs from other models of communicating behaviour mainly in its treatment of mobility. The movement of a piece of data inside a computer program is treated exactly the same as the transfer of a message - or indeed an entire computer program - across the internet. One can also describe networks which reconfigure themselves.
The calculus is very simple but powerful; its most prominent ingredient is the notion of a name. Its theory has two important ingredients: the concept of behavioural (or observational) equivalence, and the use of a new theory of types to classify patterns of interactive behaviour. The internet, and its communication protocols, fall within the scope of the theory just as much as computer programs, data structures, algorithms and programming languages.
Die Vorbesprechung findet am Mittwoch, 21.04.2004, 13:30 Uhr im Seminarraum 528 (Geb. 45) statt.
Während der Vorlesungszeit treffen wir uns dreimal in einer Lesegruppe, und zwar am 13.5., 3.6., 24.6. und 15.7. 2004 (jeweils Donnerstag 16:15 Uhr).
Das Seminar findet dann in Blockform am Ende der vorlesungsfreien Zeit vom 4.10.-6.10.2004 (Montag bis Mittwoch) statt.
