1. Decomposition of modules over the Weyl algebra
Sammanfattning : The thesis consists of two papers that treat decomposition of modules over the Weyl algebra. In the first paper decomposition of holonomic modules is used to prove that there is a finite set of Noetherian operators that suffice to distinguish the elements in a primary ideal. LÄS MER
2. Homogenization of some problems in hydrodynamic lubrication involving rough boundaries
Sammanfattning : This thesis is devoted to the study of some homogenization problems with applications in lubrication theory. It consists of an introduction, five research papers (I–V) and a complementary appendix.Homogenization is a mathematical theory for studying differential equations with rapidly oscillating coefficients.

3. Continuity and Positivity Problems in Pseudo-differential Calculus
Sammanfattning : The paper deals with various positivity and continuity questions arising in the Weyl calculus of pseudo-differential operators. Let W be a symplectic vector space. LÄS MER
