1. G-Convergence and Homogenization of some Sequences of Monotone Differential Operators
Sammanfattning : This thesis mainly deals with questions concerning the convergence of some sequences of elliptic and parabolic linear and non-linear operators by means of G-convergence and homogenization. In particular, we study operators with oscillations in several spatial and temporal scales. LÄS MER
2. Numerical Computations with Fundamental Solutions
Sammanfattning : Two solution strategies for large, sparse, and structured algebraic systems of equations are considered. The first strategy is to construct efficient preconditioners for iterative solvers. The second is to reduce the sparse algebraic system to a smaller, dense system of equations, which are called the boundary summation equations. LÄS MER
3. Preconditioners and fundamental solutions
Sammanfattning : New preconditioning techniques for the iterative solution of systems of equations arising from discretizations of partial differential equations are considered. Fundamental solutions, both of differential and difference operators, are used as kernels in discrete, truncated convolution operators. LÄS MER
4. Accuracy, efficiency and robustness for rigid particle simulations in Stokes flow
Sammanfattning : The thesis concerns simulation techniques for systems of nano- to micro-scaled rigid particles immersed in a viscous fluid, ubiquitous in nature and industry. With negligible fluid inertia, the set of PDEs known as the Stokes equations can be used to model the hydrodynamics. LÄS MER
5. Löntagarfondsfrågan - en hegemonisk vändpunkt : En marxistisk analys
Sammanfattning : The aim of the dissertation is twofold. The primary aim is to explain how the wage-earner funds could change the way they did, from the original proposal 1975 to the carried through 1983. The second is to show the relevans of Marxist analysis today, through the application of Marxist theory on the wage-earner funds issue. LÄS MER
