1. Numerical analysis and simulation of stochastic partial differential equations with white noise dispersion
Sammanfattning : This doctoral thesis provides a comprehensive numerical analysis and exploration of several stochastic partial differential equations (SPDEs). More specifically, this thesis investigates time integrators for SPDEs with white noise dispersion. LÄS MER
2. Comparison equation treatment of the radial Schrödinger equation : theory and applications
Sammanfattning : .... LÄS MER
3. On finite element schemes for Vlasov-Maxwell system and Schrödinger equation
Sammanfattning : This thesis treats finite element schemes for two kind of problems, the Valsov-Maxwellsystem and the nonlinear Schrödinger equation. We study streamline diffusion schemes applied for numerical solution of the one and one-half dimensional relativistic Vlasov-Maxwell system. The study is made both in a priori and a posteriori settings. LÄS MER
4. Theoretical studies of lattice- and spin-polarons
Sammanfattning : Theoretical studies of lattice- and spin-polarons are presented in this thesis, where the primary tool is ab-initio electronic structure calculations. The studies are performed with employment of a variety of analytical and computational methods. LÄS MER
5. Propagation of singularities for pseudo-differential operators and generalized Schrödinger propagators
Sammanfattning : In this thesis we discuss different types of regularity for distributions which appear in the theory of pseudo-differential operators and partial differential equations. Partial differential equations often appear in science and technology. LÄS MER
