Course Description
Modern computer systems are often multi-threaded or even fully distributed over several machines and geographical locations. Instead of the well-known sequential computational models (e.g., Turing machines, λ-calculus, etc.), the key notion for describing concurrent computations is that of a process. 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 regarding the course, feel free to ask in the matrix chat or via email to the teacher of the course.
Schedule and Location
The course is taught in two sessions per week, one on Tuesdays DS4 (13.00-14.30) and Wednesdays DS3 (11.10-12.40). We're currently planning the course sessions as on-site events. If necessary, we can retract to an Online mode, probably using BigBlueButton. Exercises are intertwined with the lecture.
Acknowledgments
The first part of the lecture is based on the exposition Introduction to Bisimulation and Coinduction by Davide Sangiorgi. The slides Davide provides were an inspiration for the lecture material.
