Dirichlet branes and nonperturbative aspects of supersymmetric string and gauge theories
Abstract
In chapter 1 the author reviews some elements of string theory relevant to the rest of this report. He touches on both the classical, i.e. perturbative, string physics before Dbranes rise to prominence, and some of the progresses they brought forth. In chapter 2 he proceeds to give an exact algebraic formulation of Dbranes in curved spaces. This allows one to classify them in backgrounds of interest and study their geometric properties. He applies this formalism to string theory on CalabiYau and other supersymmetry preserving manifolds. Then he studies the behavior of the Dbranes under mirror symmetry in chapter 3. Mirror symmetry is known to be a symmetry of string theory perturbatively. He finds evidence for its nonperturbative validity when Dbranes are also considered and compute some dynamical consequences. In chapter 4 he turns to examine the consistency of curved and/or intersecting Dbrane configurations. They have been used recently to extract information about the field theories that arise in certain limits. It turns out that there are potential quantum mechanical inconsistencies associated with them. What saves the day are certain subtle topological properties of Dbranes. This resolution has implications for the conserved charges carried by the Dbranes, which he computesmore »

This resolution has implications for the conserved charges carried by the Dbranes, which he computes for the cases studied in chapter 2. In chapter 5 he uses intersecting brane configurations to study three dimensional supersymmetric gauge theories. There is also a mirror symmetry there that, among other things, exchanges classical and quantum mechanical quantities of a (mirror) pair of theories. It has an elegant realization in term of a symmetry of string theory involving Dbranes. The author employs it to study a wide class of 3d models. He also predicts new mirror pairs and unconventional 3d field theories without Lagrangian descriptions.},
