Anotace:

The course focuses on the basics of propositional and predicate logic. It starts from the semantic point of view. Based on the notion of truth, satisfiability, logical equivalence, and the logical consequence of formulas are defined. Methods for determining the satisfiability of formulas, some of which are used for automated proving, are explained. This relates to the P vs. NP problem and Boolean functions in propositional logic. In predicate logic, the course further deals with formal theories, such as arithmetics, and their models. The syntactic approach to mathematical logic is demonstrated on the axiomatic system of propositional logic and its properties. Gödel's incompleteness theorems is explained.

Cíle studia:

The goal is to learn to work in formal mathematical logic, to understand its syntax and semantics. Work with theories as axiomatic systems and derive their consequences. Know what the correctness, completeness, consistency, and decidability of theories mean, and which problems are relied to. Understand Boolean algebra as a generalization of propositional logic.
