Symmetric group, its representation and applications in molecular and quantum chemistry
Krchová, Lenka ; Tomáš, Jiří (referee) ; Kureš, Miroslav (advisor)
The subject of this bachelor thesis is the study of the symmetric groups, their representation and application in molecular chemistry. At first, the particular terms from the algebra are defined, which are which are necessary to define the concept of a group. Many of them are suúpplemented by pictures for clarity and better understanding. Then, the algebraic structures, which are accompanied by clear schemes and concrete examples, are explained. Also, the symmetric groups are demonstrated on the example of the square and triangle. After that, the reader gets into the chapter about the representation of final groups where the structure of the work is similar. First, the relevant terms are defined and then the author focuses on Young's diagrams. These are meticulůously described, few examples are mentioned and so is their working procedure. The last part of the bachelor thesis is dedicated to the operators in quantum chemistry, their principles and functions for two and three particles. This too is accompanied by examples.

Wreath products of symmetric groups and enumeration of Sudoku squares
Kašpar, Jakub ; Drápal, Aleš (advisor) ; Tůma, Jiří (referee)
The thesis systematizes the enumeration of essentially different Sudoku squares using Burnside's lemma. This enumeration significantly depends on the description of conju- gacy classes of symmetry group of Sudoku square, which was in previous works provided only with the strong help of mathematical software. The first chapter of this thesis sums up facts about a group action and about conjugacy classes and proposes the descrip- tion of conjugacy classes of wreath product, in the second chapter Sudoku square of symmetric group is formally defined and with the help of presented theory are counted representatives and sizes of its conjugacy classes. 1
