Modelling of Concurrent Systems (SS 2018)

Lecturer and Tutor:
Dr. Harsh Beohar

Technical content

The following topics are expected to be covered during this course:

  • Transition system
  • Behavioral equivalences: trace equivalence, failure equivalence, bisimulation equivalence
  • Hennessy-Milner Logic
  • Process algebra - TCP, (CCS and CSP)
  • Formal specification of hybrid system
