Learning objectives:
The aim of the subject is to improve the students' knowledge of the basic mathematical structures that are often utilized in different branches of informatics. In addition to the classical algebraic structures also foundations will be discussed of the mathematical logic, the theory of Banach and Hilbert spaces, and the graph theory.
Description:
Formal theories, predicate logic, intuitionistic, modal and temporal logics, algebraic structures with one and with two binary operations, universal algebras, topological and metric spaces, Banach and Hilbert spaces, undirected graphs, directed graphs and networks.
Learning outcomes and competences:
The students will improve their knowledge of the basic algebraic structures employed in informatics. This will enable them to better understand the theoretical foundations of informatics and conduct research work in the field.
Syllabus of lectures:

• Propositional logic, formulas and their truth, formal system of propositional logic, provability, completeness theorem.
• Language of predicate logic (predicates, kvantifiers, terms, formulas) and its realization, truth and validity of formulas.
• Formal system of 1st order predicate logic, correctness, completeness and compactness theorems, prenex  form of formulas.
• Universal algebras and their types, subalgebras and homomorphisms, congruences and factoralgebras, products, terms and free algebras.
• Groupoids, semigroups, subgroupoids, homomorphisms, factorgroupoids and free semigroups.
• Groups, subgroups and homomorphisms, factorgroups and cyclic groups, free and permutation groups.
• Rings, homomorphisms, ideals, factorrings, fields.
• Polynomial rings, integral domains and divisibility, finite fields.
• Metric spaces, completeness, normed and Banach spaces.
• Unitar and Hilbert spaces, orthogonality, closed orthonormal systems and Fourier series.
• Trees and spanning trees, minimal spanning trees (the Kruskal's and Prim's algorithms), vertex and edge colouring.
• Directed graphs, directed Eulerian graphs, networks, the critical path problem (Dijkstra's and Floyd-Warshall's algorithms).
• Networks, flows and cuts in networks, maximal flow and minimal cut problems, circulation in networks.
