Course details

# Logic

LOG Acad. year 2012/2013 Summer semester 5 credits

In the course, the basics of propositional and predicate logics will be taught. First, the students will get acquainted with the syntax and semantics of the logics, then the logics will be studied as formal theories with an emphasis on formula proving. The classical theorems on correctness, completeness and compactness will also be dealt with. After discussing the prenex forms of formulas, some properties and models of first-order theories will be studied. At the end of the course, we will deal with the undecidability of first-order theories resulting from the well-known Gödel incompleteness theorems.

Subject specific learning outcomes and competences

The students will acquire the ability of understanding the principles of axiomatic mathematical theories and the ability of exact (formal) mathematical expression. They will also learn how to deduct, in a formal way, new formulas and to prove given ones. They will realize the efficiency of formal reasonong and also its limits.

Generic learning outcomes and competences

The students will learn exact formal reasoning to be able to devise correct and efficient algorithms solving given problems. They will also acquire an ability to verify the correctness of given algorithms (program verification).

Learning objectives

The aim of the course is to acquaint students with the basic methods of reasoning in mathematics. The students should refresh their knowledge of fundamentals of propositional logic and learn about the axiomatic approach about the logic. But they should mainly learn about general principles of  predicate logic and, consequently, acquire the ability of exact mathematical reasoning and expression. At the end of the course, the students will get acquainted with the problematic of incompeteness of predicate logic including the famous Gödel incompleteness theorems.

Prerequisite kwnowledge and skills

The knowledge acquired in the bachelor's study course "Discrete Mathematics" is assumed.
