Final Consultation
I'm offering a final consultation on Monday, July 28 at 13.00 in room APB 3027.
Course Description
Modern computer systems are often multi-threaded or even fully distributed over several machines and geographic locations. Instead of computation (e.g., in Turing machines, λ-calculus, etc.), the key notion for describing concurrent computations is interaction leading to the concept of processes. In this course, we study several phenomena occurring in concurrent computations using process calculi, for which we will define and analyze their formal semantics. As one of the key aspects, we ask when two processes are considered to be equivalent. Subsequently, we give an (incomplete) list of topics we strive for throughout the course.
- From sequential to parallel processes (LTS, CCS)
- Bisimulation and Coinduction
- From sequential to concurrent processes (Petri nets)
- Mobile processes (the π-calculus)
- Expressive power of process calculi
- Data-Aware Processes

If you have questions about the course, feel free to ask in the matrix chat or email the teacher(s).
Schedule and Location
The course is taught in two sessions per week,
* weekly lecture sessions will happen on Mondays DS4 (13.00-14.30) * weekly exercise sessions happen on Tuesdays DS3 (11.10-12.40).All the sessions take place in APB E005. We're currently planning the course sessions as on-site events. If necessary, we can retract to an Online mode, probably using Zoom.
