Black holes are among the most intriguing objects in the Universe. When isolated and stationary, they are described by the simple Kerr(-Newman) metric. However, astro- physical black holes are seldom isolated; in fact, we ...

Continuum mechanics and thermodynamics have been used in many fields from sci- ence to industry to medicine. While simple materials have already been described, for instance by the famous Navier-Stokes equations, more ...

In this thesis, we focus on equivalence tests used in situation where we need to prove the validity of statements usually framed as null hypothesis. We present a procedure used for solving these tests called the confidence ...

30. prosinec 2023 This thesis studies novel approaches to learning of physical models, incorporat- ing constraints and optimizing path dependent loss functions. Recent advances in deep learning and artificial intelligence ...

This thesis deals with the method of least squares with matrices that are partly dense and partly sparse. The first part of the thesis describes the method of least squares and its basic properties. Then theoretical ...

Braid groups involve certain problems that enable the construction of trapdoor func- tions for the purposes of asymmetric cryptography. Specifically, the conjugacy problem has shown potential in this direction, leading to ...

In this thesis, we will formally define objects in Euclidean geometry, lattices and affine lattices and use them to describe objects in integer trigonometry. We will prove that the described objects in integer trigonometry ...

John H. Conway has introduced the topograph, a graph containing all possible bases of Z2 as its edges. This work aims to properly define this topograph and prove its key properties. In addition, we will delve into the ...

We can color knots by various finite quandles and check if they have non-trivial coloring. If so, we can say that the knot is not an unknot. However, we will focus on quandles that always give trivial coloring. It will ...

The protoplanetary disk DoAr 44 (Haro 1-16, V2062 Oph) is a pre-transitional disk in the Ophiuchus star-forming region. A large observational dataset is available, including ALMA complex visibilities, VLTI/GRAVITY continuum ...

The main goal of this thesis is to introdude to readers the concept of weak measure- ments in quantum mechanics. Firstly a model of indirect measuremnts is established as an alternative to Von Neumann measurement postulate. ...

In this thesis, we study commutative noetherian rings using homological methods. We characterize regular local rings as rings with finite global dimension and show that they are stable under localization. After this we go ...

We describe a method by which it is possible to find the dynamics of a spin current in a spintronic terahertz emitter or other emitters derived from it. This method takes an ex- perimental emission measurement from time-domain ...

In this thesis we familiarize the reader with the fundamental notions of tilting theory. Building on those, we formulate and prove two major results of classical tilting theory, Brenner-Butler theorem and Bongartz lemma. ...

The aim of this thesis is to familiarise the reader with the concept of a C-filtration, to show properties of special instances of C-filtrations and to construct structures corresponding to general C-filtrations. The first ...

The method of Smoothed Particle Hydrodynamics is applied to the phenomenon of mountain waves - atmospheric internal gravity waves generated by flows over topogra- phy. General aspects of the method and the alternative ...

In this thesis, we study relational clones on a two-element domain (here- inafter just "relational clones"). Firstly, we provide an alternative, elementary, and purely relational proof of the famous characterization of all ...

CuMnAs is an antiferromagnet in which the possibility of writing and reading in- formation using short electrical or optical pulses has already been demonstrated. This recording represents a switching between different ...

We fix a specific action of the multiplicative group of complex numbers on a product of projective lines and examine the structure of its orbits. It turns out that the Chow quotient is isomorphic to permutohedral variety. ...

The work is focused on the structure of triangulations of combinatorial surfaces. By analyzing several local reduction moves and one global move, several known results are proven in a new way. This includes the fundamental ...

In this thesis, we utilize the discrete-state-in-continuum model and pro- jection operator formalism, successfully used to describe inelastic electron- molecule collisions, to model resonant electron photodetachment. An ...

The aim of the thesis is to give complete and thorough proofs of some well-known results from the measure theory. Oftentimes, arguments from functional analysis will be used to prove these results. For example, we will use ...

The topic of this thesis is scattering in the model 2D potential with symetry given by the C3v group. Used potential is based on the Henon-Heiles potential, which is known as a typical example of a potential with chaotic ...
