6. Strings, Conformal Field Theory and Noncommutative Geometry
Sammanfattning : This thesis describes some aspects of noncommutative geometry and conformal field theory. The motivation for the investigations made comes to a large extent from string theory. This theory is today considered to be the most promising way to find a solution to the problem of unifying the four fundamental interactions in one single theory. LÄS MER
7. Aspects of Yang-Mills Theory : Solitons, Dualities and Spin Chains
Sammanfattning : One of the still big problems in the Standard Model of particle physics is the problem of confinement. Quarks or other coloured particles have never been observed in isolation. Quarks are only observed in colour neutral bound states. The strong interactions are described using a Yang-Mills theory. LÄS MER
8. Studies in field theory : supersymmetry and torsion potentials
Sammanfattning : This report contains introductions to and summaries of the papers which constitute my thesis. These papers treat four different topics: The first of these is the superspace treatment of the linear multiplet in six space-time dimensions, in particular the solution of the constraint for this multiplet.

9. Geometry and Critical Configurations of Multiple Views
Sammanfattning : This thesis is concerned with one of the core problems in computer vision, namely to reconstruct a real world scene from several images of it. The interplay between the geometry of the scene, the cameras and the images is analyzed. LÄS MER
10. Hopf and Frobenius algebras in conformal field theory
Sammanfattning : There are several reasons to be interested in conformal field theories in two dimensions. Apart from arising in various physical applications, ranging from statistical mechanics to string theory, conformal field theory is a class of quantum field theories that is interesting on its own. First of all there is a large amount of symmetries. LÄS MER
