These lectures provide an introduction to the microscopic description of branes in curved backgrounds. After a brief reminder of the flat space theory, the basic principles and techniques of (rational) boundary conformal field theory are presented in the second lecture. The general formalism is then illustrated through a detailed discussion of branes on compact group manifolds. In the final lecture, many more recent developments are reviewed, including some results for non-compact target spaces… 

D-Branes in Noncommutative Field Theory

A mathematical introduction to the classical solutions of noncommutative field theory is presented, with emphasis on how they may be understood as states of D-branes in Type II superstring theory.

D-branes in N = 2 WZW models

Cosmology with branes wrapping curved internal manifolds

In this paper we first derive solutions which can be interpreted as branes wrapping nontrivial curved manifolds, and then study their cosmological implications. We find that at early times the branes

K-Theory from a physical perspective

This is an expository paper which aims at explaining a physical point of view on the K-theoretic classification of D-branes. We combine ideas of renormalization group flows between boundary conformal

Non-compact string backgrounds and non-rational CFT

Brane bulk couplings and condensation from REA fusion

The physical meaning of the Reflection Equation Algebras of [1] is elucidated in the context of Wess–Zumino–Witten D-brane geometry, as determined by couplings of closed-string modes to the D-brane.

A mathematical formalism for the Kondo effect in Wess-Zumino-Witten branes

In the paper, we adapt our previous formalism for a mathematical treatment of branes to include processes, specifically the Kondo flow for Wess-Zumino-Witten (WZW) branes. In this framework, we give

Boundary action of the H + 3 model

We find the boundary action for Euclidean AdS2 D-branes in H+3. This action is consistent with the D-branes' symmetries and with the H+3-Liouville relation for disc correlators. It can be used for

YM on the dielectric brane: a D0-brane tale

Discrete D-branes in AdS 3 and in the 2d black hole

I show how the AdS2 D-branes in the Euclidean AdS3 string theory are related to the continuous D-branes in Liouville theory. I then propose new discrete D-branes in the Euclidean AdS3 which

Tasi lectures on D-branes

This is an introduction to the properties of D-branes, topological defects in string theory on which string endpoints can live. D-branes provide a simple description of various nonperturbative

D-branes and Deformation Quantization

In this note we explain how world-volume geometries of D-branes can be reconstructed within the microscopic framework where D-branes are described through boundary conformal field theory. We extract

Brane Dynamics in CFT Backgrounds

In this note we discuss bound states of un- or meta-stable brane configurations in various non-trivial (curved) backgrounds. We begin by reviewing some known results concerning brane dynamics on

D-brane charges in five-brane backgrounds

We discuss the discrete k D-brane charges (twisted K-theory charges) in five-brane backgrounds from several different points of view. In particular, we interpret it as a result of a standard Higgs

on D-branes

This is an introduction to the physics of D-branes. Topics covered include Polchinski’s original calculation, a critical assessment of some duality checks, D-brane scattering, and effective

Lectures on non-BPS Dirichlet branes

A comprehensive introduction to the boundary state approach to Dirichlet branes is given. Various examples of BPS and non-BPS Dirichlet branes are discussed. In particular, the non-BPS states in the

D-branes and the noncommutative torus

We show that in certain superstring compactifications, gauge theories on noncommutative tori will naturally appear as D-brane world-volume theories. This gives strong evidence that they are

D-branes, B fields and twisted K theory

In this note we propose that D-brane charges, in the presence of a topologically non-trivial B-field, are classified by the K-theory of an infinite dimensional C*-algebra. In the case of B-fields

Flux stabilization of D-branes

We explain how D-branes on group manifolds are stabilized against shrinking by quantized worldvolume U(1) fluxes. Starting from the Born-Infeld action in the case of the SU(2) group manifold we

D-BRANES IN AN AdS3 BACKGROUND ∗

We study the possible D-brane configurations in an AdS3 × S3 × T4 background with a NS-NS B field. We use its WZW model description and the boundary state formalism, and we analyse the bosonic and
