1. Twisting and Gluing : On Topological Field Theories, Sigma Models and Vertex Algebras
Sammanfattning : This thesis consists of two parts, which can be read separately. In the first part we study aspects of topological field theories. We show how to topologically twist three-dimensional N=2 supersymmetric Chern-Simons theory using a contact structure on the underlying manifold. LÄS MER
2. Twisting and Turning in Six Dimensions
Sammanfattning : This thesis investigates certain aspects of a six-dimensional quantum theoryknown as (2,0) theory. This theory is maximally supersymmetric and conformal,making it the most symmetric higher dimensional quantum theory known. It hasresisted an explicit construction as a quantum field theory yet its existence can beinferred from string theory. LÄS MER
3. Supersymmetric Localization : A Journey from Seven to Three Dimensions
Sammanfattning : Quantum Field Theory has been a dominating framework in elementary particle physics during the last century. Within this framework, supersymmetric theories have attracted a lot of attention due to their mathematical structure, simplicity and insight into the problems of unification, dark matter and hierarchy.

4. (2,0) Theory and Higher Spin: Twisting, Turning and Spinning Towards Higher Energies
Sammanfattning : This thesis investigates an enigmatic six-dimensional quantum theory known as (2,0) theory and a three dimensional conformal theory of higher spin. The former has resisted an explicit construction as a quantum field theory, yet its existence can be inferred from string theory and M-theory where it plays a prominent role. LÄS MER
5. Field Theories with a Twist
Sammanfattning : This thesis deals with topological field theories derived from maximally supersymmetric gauge theories. The main part of this work is the three appended research papers, each of which investigates some different aspect of these theories. LÄS MER
