Introduction to Supersymmetry
(Masteroppgave/UIS-TN-IMF/2020;, Master thesis, 2020-06)This thesis covers the mathematical foundations of supersymmetry, and looks at the simplest non-trivial example of supersymmetry in physics, the Wess-Zumino model. On the way we will also explicitly calculate the Poincar´e ... -
Invariant characterization of Szekeres models with positive cosmological constant
(Peer reviewed; Journal article, 2022-07)We present an invariant characterization of black holes in the Szekeres spacetime with positive cosmological constant. In the formation of the black holes, we locate geometric horizons, and show that they coincide with the ... -
An Invariant Characterization of the Levi-Civita Spacetimes
(Peer reviewed; Journal article, 2021-08)In the years 1917–1919 Tullio Levi-Civita published a number of papers presenting new solutions to Einstein’s equations. This work, while partially translated, remains largely inaccessible to English speaking researchers. ... -
Investigation of crystal field, magnetic frustration and magnetization reversal effects in 4f and 3d oxides
(PhD thesis UiS;, Doctoral thesis, 2022-09)This thesis deals with the investigation of single-ion excitations, magnetic frustration, and magnetization reversal phenomena. We have employed neutron scattering, μ+SR, and computational methods for these studies. Inverse ... -
Investigation of glitches induced by single-crystal diamond compound refractive lenses based on crystal orientation
(Peer reviewed; Journal article, 2019)Single-crystal diamond is considered as an ideal material for compound refractive lenses (usually abbreviated to “CRLs”) mainly due to its stability when bathed in strong X-ray radiation. Since CRLs come into operation by ... -
An Investigation of Second-Order Finite Volume Methods for Field-scale Reservoir Simulation
(PhD thesis UiS;, Doctoral thesis, 2024)This thesis focuses on improving the accuracy of numerical simulation of flow in subsurface reservoirs by using second-order finite volume methods. The first-order finite volume method, commonly used in reservoir simulation, ... -
Involutions of Quadrics
(Masteroppgave/UIS-TN-IMF/2020;, Master thesis, 2020-07-09)In the introductory chapter, we will explain briefly what all this work is about. First is worthy to mention that the most included area is algebraic geometry, which of course is a combination of algebra and linear algebra. ... -
Konvergens av Fourier rekker i Hilbert rom - en introduksjon til sampling teori.
(Master thesis, 2021)Klassisk kalkulus som omhandler studie av kontinuerlig forandring kan spores helt tilbake til 1600 tallet. Derimot mangler klassisk kalkulus evnen til å tilstrekkelig transformere naturlige prosesser som lyd, radiobølger ... -
Kortspillet SET og dets underliggende matematikk
(Bachelor thesis, 2021)SET er et høyt priset kortspill hvor hvert kort har objekter med forskjellig fyll, farge og fasong. Målet med spillet er å finne SET som består av tre kort hver som følger en bestemt regel for hvordan de kan slås sammen ... -
Kumada-Corriu coupling in synthesis of PAHs
(Master thesis, 2022)The thesis explores the Kumada-Corriu coupling reaction as a possible handle to further functionalize PAHs. The starting material used was different types of triflate bearing PAHs. An attempt at preparing phenanthren-9-yl ... -

Lattice Monte Carlo simulation and phase transitions in scalar field theories
(Masteroppgave/UIS-HF-IMF/2019;, Master thesis, 2019-06-15)The cubic anisotropy model is a simple scalar field theory with a phase transition of either first- or second order depending on the values of its parameters, with similarities to the electroweak phase transition that ... -
Lattice study of static quark-antiquark interactions in dense quark matter
(Peer reviewed; Journal article, 2019-05)In this paper we study the interactions among a static quark-antiquark pair in the presence of dense two-color quark matter with lattice simulation. To this end we compute Polyakov line correlation functions and determine ... -
Learning the nonlinear flux function of a hidden scalar conservation law from data
(Peer reviewed; Journal article, 2023-10)Nonlinear conservation laws are widely used in fluid mechanics, biology, physics, and chemical engineering. However, deriving such nonlinear conservation laws is a significant and challenging problem. A possible attractive ... -
Left-Invariant Pseudo-Riemannian Metrics on Lie Groups
(Masteroppgave/UIS-TN-IMF/2020;, Master thesis, 2020)n differential geometry and mathematical physics, there is interest in left-invariant pseudo-Riemannian metrics on Lie groups. We learn and review Lie theory, representation theory, geometric invariant theory, and differential ... -
Lil3 dimerization and chlorophyll binding in Arabidopsis thaliana
(Peer reviewed; Journal article, 2015)The two-helix light harvesting like (Lil) protein Lil3 belongs to the family of chlorophyll binding light harvesting proteins of photosynthetic membranes. A function in tetrapyrrol synthesis and stabilization of geranylgeraniol ... -
