1. Low-dimensional cohomology of current Lie algebras
Sammanfattning : We deal with low-dimensional homology and cohomology of current Lie algebras, i.e., Lie algebras which are tensor products of a Lie algebra L and an associative commutative algebra A. LÄS MER
2. Simple Modules over Lie Algebras
Sammanfattning : Simple modules are the elemental components in representation theory for Lie algebras, and numerous mathematicians have worked on their construction and classification over the last century. This thesis consists of an introduction together with four research articles on the subject of simple Lie algebra modules. LÄS MER
3. Periodisations of contragredient Lie superalgebras and their presentations
Sammanfattning : .... LÄS MER
4. Strings, Branes and Symmetries
Sammanfattning : Recent dramatic progress in the understanding of the non-perturbative structure of superstring theory shows that extended objects of various kinds, collectively referred to as p-branes, are an integral part of the theory. In this thesis, comprising an introductory text divided in two parts and seven appended research papers (Papers I-VII), we study various aspects of p-branes with relevance for superstring theory.

5. Canoniical involutions and bosonic representations of three-dimensional lie colour algebras
Sammanfattning : .... LÄS MER
