Sharp bounds on the height of some arithmetic Fano varieties
(2023)In the framework of Arakelov geometry one can define the height of a polarized arithmetic variety equipped with an hermitian metric over its complexification. When the arithmetic variety is Fano, the complexification is ... 
New AIbased methods for studying antibioticresistant bacteria
(20231103)Antibiotic resistance is a growing challenge for human health, causing millions of deaths worldwide annually. Antibiotic resistance genes (ARGs), acquired through mutations in existing genes or horizontal gene transfer, ... 
Efficient training of interpretable, nonlinear regression models
(20230630)Regression, the process of estimating functions from data, comes in many flavors. One of the most commonly used regression models is linear regression, which is computationally efficient and easy to interpret, but lacks ... 
The influence of numbers when students solve equations
(2023)Is it possible that some students’ primary difficulty with equationsolving is neither handling the literal symbols nor the equality, but the numbers used as coefficients? It is well known that many students find algebra ... 
Numerical approximation of mixed dimensional partial differential equations
(2023)In this thesis, we explore numerical approximation of elliptic partial differential equations posed on domains with a high number of interfaces running through. The finite element method is a wellstudied numerical method ... 
Limit Theorems for Lattices and Lfunctions
This PhD thesis investigates distributional questions related to three types of objects: Unimodular lattices, symplectic lattices, and Hecke Lfunctions of imaginary quadratic number fields of class number 1. In Paper ... 
Sketches of Noncommutative Topology
(20221107)This thesis thematically divided into two parts. In the first part we are mastering C*isomorphism problem by using various techniques applied to different examples of noncommutative algebraic varieties. In the second part ... 
Global residue currents and the Ext functors
(20220909)This thesis concerns developments in multivariable residue theory. In particular we consider global constructions of residue currents related to work by Andersson and Wulcan. In the first paper of this thesis, we consider ... 
Mathematical Modelling of Cellular Ageing: a MultiScale Perspective
(20220419)In a growing and increasingly older population, we are progressively challenged by the impact of ageing on individuals and society. The UN declared the years 20212030 as the Decade of Healthy Ageing, highlighting the ... 
On the mathematics of the onedimensional HegselmannKrause model
(20220119)This thesis contains three papers, which all in different ways concern the asymptotics of the HegselmannKrause model in opinion dynamics. In this model a set of conformist agents repeatedly and synchronously replace their ... 
Combinatorics of solvable lattice models with a reflecting end
(20210421)I den här avhandlingen studerar vi några exakt lösbara, kvantintegrerbara gittermodeller. Izergin bevisade en determinantformel för partitionsfunktionen till sexvertexmodellen på ett gitter av storlek n × n med Korepins ... 
Network modeling and integrative analysis of highdimensional genomic data
(20200507)Genomic data describe biological systems on the molecular level and are, due to the immense diversity of life, highdimensional. Network modeling and integrative analysis are powerful methods to interpret genomic data. ... 
The construction, analysis and validation of mechanistic mathematical models of protein kinetics in the context of replicative ageing in budding yeast
(20200504)Mathematical modelling constitutes a forceful tool for elucidating properties of biological systems. Using theoretical approaches in combination with experimental techniques it is possible to study specific molecular aspects ... 
Geometrical and percolative properties of spatially correlated models
(20200310)This thesis consists of four papers dealing with phase transitions in various models of continuum percolation. These models exhibit complicated dependencies and are generated by different Poisson processes. For each such ... 
Learning to solve problems that you have not learned to solve: Strategies in mathematical problem solving
(20190816)This thesis aims to contribute to a deeper understanding of the relationship between problemsolving strategies and success in mathematical problem solving. In its introductory part, it pursues and describes the term ... 
Spectral properties of elliptic operators in singular settings and applications
(20190522)The present thesis is focused on the investigation of the spectral properties of the linear elliptic operators in the presence of singularities. It is divided into three chapters. In the first chapter, we consider ... 
Efficient Adaptive Algorithms for an Electromagnetic Coefficient Inverse Problem
(20170608)This thesis comprises five scientific papers, all of which are focusing on the inverse problem of reconstructing a dielectric permittivity which may vary in space inside a given domain. The data for the reconstruction ... 
Resampling in network modeling of highdimensional genomic data
(University of Gothenburg and Chalmers University of Technology, 2017)Network modeling is an effective approach for the interpretation of highdimensional data sets for which a sparse dependence structure can be assumed. Genomic data is a challenging and important example. In genomics, ...
