2. On the Extension and Wedge Product of Positive Currents
Sammanfattning : This dissertation is concerned with extensions and wedge products of positive currents. Our study can be considered as a generalization for classical works done earlier in this field. Paper I deals with the extension of positive currents across different types of sets. LÄS MER
3. Topics in analytic theory of partial differential equations
Sammanfattning : The thesis consists of three papers I, II III devoted to some topics in analytic theory of partial differential equations. The main paper is II. In this paper we study a version of the classical problem on the convergence of formal solutions of systems of partial differential equations. LÄS MER
4. On Propagation of Boundary Continuity for Domains in Complex Space
Sammanfattning : We consider continuity properties of analytic functions in bounded domains in complex space, focusing on the following two questions:Question 1. Given a bounded domain G in complex affine n-space. LÄS MER
5. 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
