Supersymmetric gauge theories from D3-branes on singularities
In this thesis we study four-dimensional supersymmetric gauge theories and their string theory realization. After an introduction and a brief review of some basic concepts at the interface of gauge theories and string theory, we begin by examining the duality cascade phenomenon for quiver gauge …

Aspects of double geometry and supersymmetric gauge theories
… The second part focuses on exact results in supersymmetric gauge theories. We first discuss T-duality symmetry of string theory from various perspectives. We next review the manifest-duality-symmetric formulation of low-energy effective actions: double field theory (DFT) and its …

Low Dimensional Supersymmetric Gauge Theories and Mathematical Applications
This thesis studies N=(2,2) gauged linear sigma models (GLSMs) and three-dimensional N=2 Chern-Simons-matter theories and their mathematical applications. After a brief review of GLSMs, we systematically study nonabelian GLSMs for symplectic and orthogonal Grassmannians, following up a proposal in …

On algebraic singularities, finite graphs and D-brane gauge theories : a string theoretic perspective -- with a digression on string field theory
… between the construction of 4-dimensional supersymmetric gauge theories and resolution of algebraic singularities, from the perspective of String Theory. We review in detail the requisite background in both the mathematics, such as orbifolds, symplectic quotients and quiver representations, …

On extended supersymmetry in two and four dimensions.
We study the relationship between gauge theories in two and four dimensions with N = 2 supersymmetry. This includes the duality between their moduli spaces, comparison of Bogomolny-Prassad-Somerfield (BPS) spectra, study of instanton configurations, and other aspects. On they way we use various …

Holography, large N, and supersymmetry on the lattice
<p>Lattice studies of strongly coupled gauge theories started with the pioneering work of Wilson. The success of lattice QCD since then has improved our understanding of strong dynamics, crucial for a proper understanding of many interesting phenomena in Physics. However, it is now known that the …

Supersymmetric backgrounds of M-theory and AdS4/CFT3 correspondence
We analyse the most general N = 2 supersymmetric solutions of d = 11 supergravity consisting of a warped product of four-dimensional anti-de-Sitter space with a sevendimensional Riemannian manifold Y7. We show that the necessary and sufficient conditions for supersymmetry can be phrased in terms of …

D-branes on Calabi-Yau Spaces
… Compactifications of type II string theories on these spaces to which D-branes are added lead to N = 1 supersymmetric gauge theories on the world-volume of these D-branes. Both the Calabi–Yau spaces and the D-branes have in general a moduli space. We examine the dependence of the …
