Learning Outcomes

The course is based on the first and second chapter of Gaisi Takeuti’s in 1987 published book Proof Theory (Studies in Logic and the Foundations of Mathematics). The first chapter introduces Gentzen's sequent calculi for Intuitionistic Logic (LJ) and Classical Logic (LK) and proves Gentzen's cut-elimination theorem as well as completeness theorems for both LJ and LK. The second chapter is Gentzen's second proof of the eliminability of essential cuts from a derivation of the empty sequent in Peano Axioms. All these results are needed to prove the main result of the course: Gödel’s two incompleteness theorems and Tarski’s teorem. After completing the course, the student knows what the fundamental results of mathematical logic are, in particular the proof theoretical approach, Completeness of propostional and first order logc, Gödel's incompleteness theorems, Tarskis theorem, Löwenheim-Skolem theorem, Herbrand theorem. A rudimentary understanding of proof theory is formed, and the student is able to apply some basic results and knows some details of basic techniques such as truth tables.

The course differs in year 2014 lectured Mathematical logic course; the starting point is now proof theoretical, in 2014 it was the model theorical. The main results are the same, however.
