Supernova constraints on dark flavored sectors
(Peer reviewed; Journal article, 2021-06)Proto-neutron stars forming a few seconds after core-collapse supernovae are hot and dense environments where hyperons can be efficiently produced by weak processes. By making use of various state-of-the-art supernova ... -
Survival Analysis using Cox Regression on Breast Cancer Data
(Master thesis, 2020-06)In this report, survival data from a german breast cancer study has been analysed using the programming software R. For the 686 female patients participating in the study, the value of eight explanatory variables were ... -
Symmetric teleparallel geometries
(Peer reviewed; Journal article, 2022)In teleparallel gravity and, in particular, in F(T) teleparallel gravity, there is a challenge in determining an appropriate (co-)frame and its corresponding spin connection to describe the geometry. Very often, the ‘proper’ ... -
Symmetry and Equivalence in Teleparallel Gravity
(Peer reviewed; Journal article, 2020-07)In theories such as teleparallel gravity and its extensions, the frame basis replaces the metric tensor as the primary object of study. A choice of coordinate system, frame basis, and spin-connection must be made to obtain ... -
Syntese og fotonedbrytningsevaluering av aminoalkoholer og oksazolidiner
(Master thesis, 2023)Synteseforskning på etanolaminer og deres derivater, oksazolidiner, representerer bare en del av den større innsatsen for å bekjempe antibiotikaresistens og utvikle nye strategier for behandling. Antibiotikaresistens er ... -
T3-invariant heterotic Hull-Strominger solutions
(Peer reviewed; Journal article, 2021-01)We consider the heterotic string on Calabi-Yau manifolds admitting a Strominger-Yau-Zaslow fibration. Upon reducing the system in the T3-directions, the Hermitian Yang-Mills conditions can then be reinterpreted as a complex ... -
Tales from Wonderland
(Doctoral thesis, 2020-06)Knowing that the Universe is quite isotropic, one may, as already discussed in Chapter 1, wonder how likely such a Universe is. We take the following research question. Question 1. Is the asymptotic future of a cosmology ... -
The card game SET and finite geometry
(Bachelor thesis, 2023)This thesis explores the underlying mathematics of the card game SET, which is a fast-paced pattern recognition game played with 81 cards. The game involves making SETs of three cards with certain compatibility conditions ... -

The dark matter freeze out and beyond
(Master thesis, 2022)Evidence of the existence of dark matter has been found due to deviations of gravitational motion of astronomical objects. We want to investigate the dark matter topic, which is constantly evolving due to the fast development ... -
The Fourier transform and its applications to partial differential equations.
(Master thesis, 2021)In this master’s thesis I will introduce a way to solve partial differential equations and boundary value problems by transforming signals from a time domain to a frequency domain, and back. This algorithm is ... -
The reasons for the collapse of the Tacoma Narrows Bridge and the lessons for the classroom
(Bachelor thesis, 2022)On 7 November 1940, a historical event occurred for suspension bridge construction and aerodynamic engineering around suspension bridges. Engineers investigating the event concluded the bridge collapsed due to high winds ... -
The Unicity of a Blow-down.
(Master thesis, 2023)In algebraic geometry, projective varieties are classified up to isomorphism. This involves classifying the varieties up to birational equivalence and classifying nonsingular varieties in each equivalence class up to ... -
Thermalization and dynamical spectral properties in the quark-meson model
(Peer reviewed; Journal article, 2020-07)We investigate the nonequilibrium evolution of the quark-meson model using two-particle irreducible effective action techniques. Our numerical simulations, which include the full dynamics of the order parameter of chiral ... -
Thermalization of non-Abelian gauge theories at next-to-leading order
(Peer reviewed; Journal article, 2022)We provide the first next-to-leading-order (NLO) weak-coupling description of the thermalization process of far-from-equilibrium systems in non-Abelian gauge theory. We study isotropic systems starting from either over- ... -
Thermalization of weakly coupled non-Abelian plasmas at next-to-leading order
(Peer reviewed; Journal article, 2023)We employ the QCD kinetic theory, including next-to-leading(NLO) order corrections in coupling constant, to study the evolution of weakly coupled non-Abelian plasmas towards thermal equilibrium. For two characteristic ... -
Thermodynamics of antiferromagnetic solids in magnetic fields
(Peer reviewed; Journal article, 2020)We analyze the thermodynamic properties of antiferromagnetic solids subjected to a combination of mutually orthogonal uniform magnetic and staggered fields. Low- temperature series for the pressure, order parameter and ... -
Thermopower in an anisotropic two-dimensional Weyl semimetal
(Journal article, 2020-01)We investigate the generation of an electric current from a temperature gradient in a two-dimensional Weyl semimetal with anisotropy in both the presence and absence of a quantizing magnetic field. We show that the anisotropy ... -
Thoughts about the utility of perturbative QCD in the cores of neutron stars – contribution to a roundtable discussion on neutron stars and QCD
(Peer reviewed; Journal article, 2022)In this contribution, I discuss the utility that perturbative QCD offers in studying the matter in the cores of neutron stars. I discuss the reasons why perturbative QCD can constrain the equation of state at densities far ... -
Tidserier for finansiell data
(Bachelor thesis, 2023)The motivation for this thesis is to grasp general theory and principles for modeling time series, for the application to financial data. By going through the theory that makes up this field and bringing that perception ...
