Drozd rings
Nytra, Jan ; Doupovec, Miroslav (referee) ; Kureš, Miroslav (advisor)
This thesis focuses on Drozd rings. In the beginning, we mention important parts of algebraic theory for the definition of these rings. In the next chapter we describe an example of Drozd ring. In the following, we concentrate on Weil algebras - it shows up, that Drozd algebras over field of real numbers are specific examples of Weil algebras. We also construct groups of algebra automorphisms for these algebras. In the last part of the thesis, we mention Lie groups, because groups of algebra automorphisms of Weil algebras are examples of Lie groups.

Affine mappings and transformations in the plane with solved examples
Barborka, Lukáš ; Zamboj, Michal (advisor) ; Jančařík, Antonín (referee)
Analytical geometry widely uses the apparatus of linear algebra, it is, of course, its natural application. The aim of this thesis is the theoretical interconnection, for many students still abstract, bases of the linear algebra with their practical application in the analyti- cal geometry, especially in affine transformations and their use in the solved examples in the plane. This thesis is intended to put concepts known from the course of Linear algebra (homomorphism, eigenvalues/eigenvectors, orthogonal matrices, transition matri- ces...) into context with practical using in the analytical geometry, whether in the form of proofs of important theorems using the linear algebra and arithmetic apparatus, or the following solved examples. The aim of the examples is to provide some insight or guidance on the solution of the same or analogous tasks. The theory and examples are in some cases supplemented with illustrations for better clarity. The work is divided into several parts for greater clarity. The introduction is repeated important concepts of linear algebra such as group, field, vector space, Euclidean space, linear mapping (homomorphism), change of coordinates matrix, eigenvalue/eigenvector of the matrix. It also switches to affine point space, affine coordinate system, transformation equation for...

Homomorphic Coordinates of Dempster’s Semigroup
Daniel, Milan
Coordinates of belief functions on two-element frame of discernment are defined using homomorphisms of Dempster’s semigroup (the algebra of belief functions with Dempster’s rule). Three systems of the coordinates (h-f, h-f0, and coordinates based on decomposition of belief functions) are analysed with a focus to their homomorphic properties. Further, ideas of generalisation of the investigated systems of coordinates to general finite frame of discernment are presented.

KAM-DIMATIA Series 2004-685 and ITI Series 2004-206. Two algorithms for general list matrix partitions
Sgall, Jiří ; Feder, T. ; Hell, P. ; Králď, D.
List matrix partitions are restricted binary list constraint satisfaction problems which generalize list homomorphisms and many graph partition problems arising, e.g., in the study of perfect graphs. Most of the existing algorithms apply to concrete small matrices, i.e., to partitions problems, provide algorithms for their solution, and discuss their implications.
