Learning objectives:
The aim of the course is to acquaint students with the basic methods of reasoning in mathematics. The students should learn about general principles of formal (axiomatic) theories and, consequently, acquire the ability of exact mathematical reasoning and expression. They should also get familiar with some important formal theories utilizied in informatics.
Description:
In the course, the basics of propositional and predicate logics  will systematically be taught  First, the students will get acquainted with the syntax and semantics of the two logics, then the logics will be studied as formal theories with an emphasis on formula proving. The classical theorems on compactness and completeness will alsom be dealt with. After discussing the prenex forms of formulas, some properties and models of first-order theories will be studied. We will also deal with the undecidability of first-order theories resulting from the well-known Gödel incompleteness theorems. Finally, some further important logics will be discussed which have applications in computer science.
Knowledge and skills required for the course:
The knowledge acquired in the bachelor's study course "Discrete Mathematics" is assumed.
Subject specific learning outcomes and competencies:
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 of a theory and to prove given ones. They will realize the efficiency of formal reasoning and also its limits.
Generic learning outcomes and competencies:
The students will learn exact formal reasoning to be able to devise a correct and efficient algorithms solving given problems. They will also acquire an ability to verify the correctness of given algorithms (program verification).
