Tuhost a Hamiltonovskost grafů

The present thesis is motivated by the study of Chvátal's t_0-tough conjecture. We recall this conjecture in the context of Hamiltonian Graph Theory. We review partial results to the conjecture, and we analyse constructions which provide lower bounds to this conjecture and to s...

Matematické modelování ve výuce na střední škole

The aim of this work is to suggest an expansion of preparation of learning materials designed for university teachers who work with students who have chosen advanced mathematics as an elective, or with high school students who are engaged in mathematics beyond compulsory curriculum...

Hošek, Radim
Numerická schémata pro rovnice vazkého stlačitelného proudění: Analýza a geometrie

The dissertation thesis presents a commented collection of research articles with results in the analysis of numerical schemes for systems that model viscous compressible fluids. They are mainly based on a pioneering work of Karper, who proved a convergence of a numerical scheme to...

Jirásek, Pavel
Podmínky kompaktnosti ve variačních metodách

This dissertation studies variational methods and compactness conditions used in them. The methods are illustrated on the boundary problems for elliptic equations.

Caggio, Matteo
Navier- Stokesovy rovnice a související problémy

The present thesis is devoted to the study of mathematical problems related to the Navier-Stokes equations in the context of mathematical rigorous derivation of models and their analysis. In particular we deal with the problem of singular limits in fl uid mechanics for compressible...

Aplikace duálních kvaternionů na vybrané problémy

In recent years, the study of quaternions has become an active research area of applied geometry, mainly due to an elegant and efficient possibility to represent using them rotations in three dimensional space. Thanks to their distinguished properties, quaternions are often used i...

Volek, Jonáš
Parciální dynamické rovnice na diskrétních prostorových oblastech

The dissertation thesis presents our recent results about the partial dynamic equations on discrete spatial domains (so-called lattices). These problems arise from the modeling of processes on spatially structured environment (e.g., cells, crystal lattices, electronic images). Consequently, we study p...

Chromatická teorie grafů

The goal of this thesis is to analyze several distinct problems regarding graph colorings. To motivate the topic, we first demonstrate that the theory of graph coloring provides useful tools for modeling a wide variety of scheduling and assignment problems. We then introduce basic&...
