1. Field Theories with a Twist
Abstract : 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. READ MORE

2. Topics in Five Dimensional Supersymmetry and Topological Quantum Field Theories
Abstract : We explore five-dimensional supersymmetric quantum field theories and topological quantum field theories. In five dimensions, we describe a framework to consistently define a supersymmetric theory on a curved spacetime manifold. READ MORE

3. BRST and Topological Gauge Theories
Abstract : In this thesis, the BRST-quantization of gauge theories is discussed. A detailed analysis of the BRST-quantization on inner product spaces is performed for a class of abelian models, including reparametrization invariant ones. General rules how to obtain physical wave functions and propagators are proposed. READ MORE

4. Twisting and Gluing : On Topological Field Theories, Sigma Models and Vertex Algebras
Abstract : 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. READ MORE

5. Localization of N=2 Field Theories: a Twisted Path Across Four Manifolds
Abstract : Supersymmetric quantum field theories provide a framework where certain physical observables can be computed exactly. In those cases, one not only has control over perturbative contributions but also over non-perturbative contributions. READ MORE
