  • 2013 Autumn/Monsoon (Aug - Dec)

Syllabus: Propositional logic: Syntax and Semantics, Applications of Propositional Calculus, Properties: functional completeness, decidability, compactness, conjunctive and disjunctive normal forms. Hintikka's lemma and model existence theorem. Semantic tableaux: soundness, completeness and decidability. Hilbert proof systems and Gentzen's sequent calculus. Predicate logic: Syntax and semantics. Applications of predicate logic. Herbrand models. Hintikka's lemma and model existence theorem. Compactness. First-order semantic tableaux: Soundness and completeness. Hilbert proof system for first-order logic and deduction theorem. Gentzen's sequent calculus for First Order Logic. First-order logic with Equality: Axioms and completeness. Normal forms. Properties: Lowenheim-Skolem theorem, Compactness, Interpolation and Definability. Some First-order theories: Presburger and Peano Arithmetic. First-order theory of reals. ZFC axioms for set theory. Limitations: Undecidability of First-order logic. Tarski's Theorem on Undefinability of Truth. Godel's Incompleteness Theorems. Suggested Reading: J.
