1. The Dirac Equation: Numerical and Asymptotic Analysis
Abstract : The thesis consists of three parts, although each part belongs to a specific subject area in mathematics, they are considered as subfields of the perturbation theory. The main objective of the presented work is the study of the Dirac operator; the first part concerns the treatment of the spurious eigenvalues in the computation of the discrete spectrum. READ MORE

3. On weak and strong convergence of numerical approximations of stochastic partial differential equations
University dissertation from Göteborg : Chalmers University of TechnologyAbstract : This thesis is concerned with numerical approximation of linear stochastic partialdifferential equations driven by additive noise. In the first part, we develop aframework for the analysis of weak convergence and within this framework weanalyze the stochastic heat equation, the stochastic wave equation, and the linearizedstochastic CahnHilliard, or the linearized CahnHilliardCook equation.

4. Propagation of Chaos for Kaclike Particle Systems
University dissertation from Göteborg : Chalmers University of TechnologyAbstract : This thesis concerns various aspects of the Kac model. The Kac model is a Markov jump process for a particle system where the total kinetic energy of the system is conserved. This particle model is connected to a limiting equation, describing the evolution of a oneparticle density, when the numbers of particles tends to infinity. READ MORE

5. Symmetries and conservation laws
University dissertation from Växjö : Växjö University PressAbstract : Conservation laws play an important role in science. The aim of this thesis is to provide an overview and develop new methods for constructing conservation laws using Lie group theory. The derivation of conservation laws for invariant variational problems is based on Noether’s theorem. READ MORE
