1. The Pseudo-Unitary Group U(p,q) in Quantum Magnonics
L3-uppsats, Uppsala universitet/MaterialteoriSammanfattning : The study of magnons is an essential part of combining quantum information science and spintronics, allowing for the investigation of quantum properties such as entanglement in solid-state devices. Magnons are commonly described using the theory of T. Holstein and H. LÄS MER
2. Adjoint-based Formulation for Shape Optimization Problems in Computational Fluid Dynamics
Master-uppsats, KTH/Matematik (Avd.)Sammanfattning : A continuous adjoint formulation for exterior optimization of Dirichlet data on the boundary for potential flow applications has been developed in this thesis. This has been performed by utilizing boundary integral methods for both the primal problem (Laplace’s equation) and for the corresponding adjoint equation (Poisson’s equation) on the unit disc.

3. Adjoint Curves of Polycons
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : In this thesis we are going to discuss polycons and their adjoint curves. We willdefine polycons as a type of polygon that allows for boundary curves of degree 2. LÄS MER
4. An operator theoretic approach to the Riemann Hypothesis
Master-uppsats, Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/MatematikcentrumSammanfattning : In 2023 an operator theoretic approach to the Prime Number Theorem was introduced by Olsen. In this thesis this approach is examined and applied to give a new, operator theoretic, proof of a different version of the Prime Number Theorem and of the Prime Number Theorem for arithmetic progressions.

5. Metric Methods in Ergodic Theory
Kandidat-uppsats, Uppsala universitet/Dynamiska system och talteoriSammanfattning : This bachelor's thesis discusses from an ergodic-theoretical perspective the "metric functional analysis" that Anders Karlsson and others have developed in the recent years. We introduce a new symbolic calculus for metric functionals which includes a notion of the adjoint of a nonexpansive map. LÄS MER
