Learning outcomes

After successful completion of the course, students are able to distinguish and to apply important concepts, techniques, and results of formal logic and computability theory. Moreover, students who pass the fianl exams should be able to understand and to explain connections between topics like incompleteness of arithmetical calculi, undecidabiltiy, formal provability and expressibility.

Subject of course

  • advanced aspects of classical first order logic as specification tool
  • proof systems for classical first order logic, including  soundness and completeness proofs 
  • elements of model theory (Löwenheim-Skolem, compactness, expressibility)
  • principles of automated theorem proving
  • methods for handling identity  
  • comparison of types of inference systems 
  • elements of modal logic: Kripke semantics, temporal logics 
  • elements of intuitionistic logic and constructive proofs
  •  computational aspects of logic
  • undecidabilty of first order logic and its consequences
  • models of computation (Turing machines, lambda calculus)
  • elementary recursion theory
  • Church-Turing thesis
  • incompleteness of arithmetic and its consequences 

Teaching methods

  • derivations in various different logical calculi
  • applying formal concepts to standard problem sets
  • mastering formal (mathematical) definitions
  • analysis of proofs of central results
  • mandatory exercises

Mode of examination

Previous knowledge

Knowledge of classical propositional logic and of basic concepts of classical first order logic (logical consequence, interpretations and model structures, satisfiability versus validity, acquaintance with various proof systems), a firm understanding of the syntax/semantic distinction, some experience with formal specification, acquaintance with a range of different programming paradigms (imperative, functional, logical),  and automata theory (finite automata, pushdown automata, Turing machines)

NB: If you don't have a firm background in logic yet, you are asked to join special repetitorium classes, which are open to all participants.
