The course assumes that you have had a basic introduction to logic already and are familiar with the following topics: syntax and semantics of both propositional and first-order logic; disjunctive and conjunctive normal forms; basic equivalences of propositional and first-order logic. These topics will only be refreshed briefly at the beginning of the course.

The main topics of the course:

  • Proof theory: sequent calculus, natural deduction, resolution; their soundness and completeness; translations between proof systems.
  • Meta-theory of first order logic: compactness, model theoy, undecidability, incompleteness of arithmetic.
  • Decision procedures for fragments of logic and arithmetic.
