1. Twisting it up the Quantum Way : On Matrix Models, qdeformations and Supersymmetric Gauge Theories
Abstract : The mathematical framework which quantum field theory constitutes has been very successful in describing nature. As an extension of such a framework, the idea of supersymmetry was introduced. This greatly simplified the mathematical description of the theories, making them more tractable. READ MORE

2. Zeroenergy states in supersymmetric matrix models
Abstract : The work of this Ph.D. READ MORE

3. Dualities, Symmetries and Unbroken Phases in String Theory : Probing the Composite Nature of the String
Abstract : The thesis treats aspects of string/Mtheory in antide Sitter spacetimes and their supersymmetric completions. By applying the AdS/CFT correspondence, as well as models of spin chains and singletons, we try to attain a better understanding of the underlying symmetries and the unbroken phases of string/Mtheory.

4. Aspects of vacuum moduli in string theory
Abstract : In this thesis we explore geometric aspects of the space of vacua in supersymmetric string compactifications. More specifically, we will look at heterotic strings compactified on CalabiYau manifolds and, separately, G2 structure manifolds. READ MORE

5. Group Extensions, Gerbes and Twisted Ktheory
Abstract : This thesis reviews the theory of group extensions, gerbes and twisted Ktheory. Application to anomalies in gauge theory is briefly discussed. The main results are presented in two appended scientific papers. READ MORE
