1. Superconformal Theories in Six Dimensions
Sammanfattning : This thesis consists of an introductory text, which is divided into two parts, and six appended research papers.The first part contains a general discussion on conformal and superconformal symmetry in six dimensions, and treats how the corresponding transformations act on space-time and superspace fields.

2. A CFT perspective on holographic correlators
Sammanfattning : Conformal symmetry is ubiquitous in physics. It emerges in a variety of situations from critical phenomena, through condensed matter systems and jets at the LHC to string theory. Conformal field theories (CFTs) describe the universal behavior underlying these very different setups. LÄS MER
3. Exceptional Lie algebras and M-theory
Sammanfattning : In this thesis we study algebraic structures in M-theory, in particular the exceptional Lie algebras arising in dimensional reduction of its low energy limit, eleven-dimensional supergravity. We focus on e8 and its infinite-dimensional extensions e9 and e10. LÄS MER
4. Maximally Supersymmetric Models in Four and Six Dimensions
Sammanfattning : We consider two examples of maximally supersymmetric models; the N=4 Yang-Mills theory in four dimensions and the (2,0) theory in six dimensions. The first part of the thesis serves as an introduction to the topics covered in the appended research papers, and begins with a self-contained discussion of principal fibre bundles and symplectic geometry.
