  • Examples of state-based systems
  • Streams, automata (Moore, Mealy, deterministic, non-deterministic), transition systems, objects, probabilistic systems, neighborhood systems
  • Description of state-based systems as co-algebras
  • Category theoretical abstractions
  • structure theory
  • bisimulations and behavioural equivalence
  • co-recursive definitions, co-inductive verification
  • terminal and co-free systems.
  • modal logics
  • completeness theorem

Qualification Goals

  • development of a basic mathematical theory for the description of state-based systems,
  • understanding category-theoretical methods and conceptual formations and applications in computer science,
  • scientific skills (recognition, formulation, problem solving, abstraction),
  • training of oral communication skills in the labs by practicing free speech and discussion in front of an audience.


Translation is missing. Here is the German original:

Keine. Empfohlen werden die Kompetenzen, die in den Modulen Theoretische Informatik und Logik vermittelt werden.

This page describes a module according to the latest valid module guide in Wintersemester 2018/19. Most rules valid for a module are not covered by the examination regulations and can therefore be updated on a semesterly basis. The following versions are available in the online module guide:

The module guide contains all modules, independent of the current event offer. Please compare the current course catalogue in Marvin.
