11. Strings, Conformal Field Theory and Noncommutative Geometry
Abstract : This thesis describes some aspects of noncommutative geometry and conformal field theory. The motivation for the investigations made comes to a large extent from string theory. This theory is today considered to be the most promising way to find a solution to the problem of unifying the four fundamental interactions in one single theory. READ MORE

12. Maximally Supersymmetric Models in Four and Six Dimensions
Abstract : 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.

13. Supersymmetric Geometries in Type IIA Supergravity
Abstract : Supergravity theory is any supersymmetric theory with a local supersymmetry parameter. This thesis undertakes the study of type IIA supergravity, a supergravity theory in ten dimensions associated with type IIA string theory. READ MORE

14. On string integrability : A journey through the two-dimensional hidden symmetries in the AdS/CFT dualities
Abstract : One of the main topics in the modern String Theory are the conjectured string/gauge (AdS/CFT) dualities. Proving such conjectures is extremely difficult since the gauge and string theory perturbative regimes do not overlap. In this perspective, the discovery of infinitely many conserved charges, i.e. READ MORE

15. (2,0) Theory and Higher Spin: Twisting, Turning and Spinning Towards Higher Energies
Abstract : 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. READ MORE
