Abstract

Several aspects concerning the physics of D‐branes in Type II flux compactifications preserving minimal 𝒩 = 1 supersymmetry in four dimensions are considered. It is shown how these vacua are completely characterized in terms of properly defined generalized calibrations for D‐branes and the relation with Generalized Complex Geometry is discussed. General expressions for superpotentials and D‐terms associated with the 𝒩 = 1 four‐dimensional description of space‐time filling D‐branes are presented. The massless spectrum of calibrated D‐branes can be characterized in terms of cohomology groups of a differential complex canonically induced on the D‐branes by the underlying generalized complex structure.

## Abstract We review recent progress in the study of non‐rational (boundary) conformal field theories and their applications to describe exact holographic backgrounds in superstring theory. We focus mainly on the example of the supersymmetric coset __SL__(2, ℝ)/__U__(1), corresponding to the two‐d

## Abstract We review some aspects of D‐instantons in intersecting D‐brane models. In particular, we present applications of the recently proposed instanton calculus to computations of charged matter superpotential couplings and corrections to the gauge kinetic function in the low energy effective
