21. Some special problems in elliptic and parabolic variational inequalities
Sammanfattning : This Licentiate Thesis is devoted above all to the investigation of variational inequalities. Chapter 1 deals with linear elliptic variational inequalities, where the operator is degenerated or singular, which involves the use of some weighted Sobolev spaces. LÄS MER
22. Convexity, Currents, and Lelong numbers
Sammanfattning : This thesis treats different aspects of convexity, both real and complex. On the real side, we study convexity in relation with certain currents. On the complex side, we study the singularities of plurisubharmonic functions. LÄS MER
23. Adaptive Finite Element Methods for Div-Curl Problems
Sammanfattning : In this thesis, we develop and apply finite element methods to problems of div-curl type, mainly from applications in electromagnetics. In particular, we focus on least-squares formulations for problems with singularities, edge elements in eddy current computations, and the implementation of the finite element method. LÄS MER
24. Tackling the Uncertainties of Event Generators
Sammanfattning : This thesis is composed of four papers, which concern Monte Carlo event generators for high energy particle physics. Precise predictions of the outcome of particle collisions are important for the exploration of the Standard Model of particle physics at collider experiments like the LHC at CERN. LÄS MER
25. Subanalytic sets in the calculus of variation
Sammanfattning : The purpose of this thesis is to develop a theory for certain extreme value problems, depending analytically on some set of parameters. In particular it aims at a description of the singularities of the extreme value functions. In this context, a central role is played by the concept of subanalytic functions (i.e. LÄS MER
