We present some preliminary investigations about the AdS2 × S2 D3-branes in AdS3 × S3. We analyse the quadratic fluctuations of the Dirac-Born- Infeld action around a given semi-classical D-brane configuration and compare them with results obtained by using conformal-field-theory techniques. We finally study classical motions of open strings attached to those D-branes and analyse the role of the spectral flow in this context. 

Anti-de Sitter D-brane dynamics

We study the anti-de Sitter D-brane dynamics in hamiltonian formulation. By exploiting the existence of certain conserved charges, we solve the equation of motion for a D1-brane in the AdS3

D-branes in lorentzian AdS3

We study the exact construction of D-branes in lorentzian AdS3. We start by defining a family of conformal field theories that gives a natural euclidean version of the SL(2,) CFT and does not

D1-brane with overcritical electric field in AdS3 and S-brane

We study aspects of Dirichlet S-branes, which are defined as Dirichlet boundary condition on a time like embedding of open strings, in general backgrounds. By applying T-duality along an isometry of

D-branes in Lorentzian AdS(3)

: We study the exact construction of D-branes in Lorentzian AdS 3 . We start by defining a family of conformal field theories that gives a natural Euclidean version of the SL(2 , R ) CFT and does not

Anti-de Sitter branes with Neveu-Schwarz and Ramond-Ramond backgrounds

We review some facts about AdS2 × S2 branes in AdS3 × S3 with a Neveu-Schwarz background, and consider the case of Ramond-Ramond backgrounds. We compute the spectrum of quadratic fluctuations in the

D-branes in AdS3 × S3 × 𝕋4 at k = 1 and their holographic duals

String theory on AdS3× S3× 𝕋4 with minimal k = 1 NS-NS flux can be described in terms of a free field worldsheet theory in the hybrid formalism. We construct various D-branes of this string theory

D-branes in some near-horizon geometries

I review some properties of D-branes in the SU(2) and SL(2,R) WZW models. I comment on a potential difficulty for the realization of `warped brane worlds' in string theory. This short note is based

Boundary states for AdS2 branes in AdS3

Supersymmetric D-branes in the D1-D5 background

We construct supersymmetric D-brane probe solutions in the background of the 2-charge D1-D5 system on M, where M is either K3 or T4. We focus on `near-horizon bound states' that preserve




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

Anti-de Sitter D-branes

We study D-branes of the SL(2,) WZW model and of its discrete orbifolds. Gluing the currents by group automorphisms leads to three types of D-branes: two-dimensional hyperbolic planes (H2), de Sitter

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

SU(2) WZW D-branes and their noncommutative geometry from DBI action

Using properties of the DBI action we find D-branes on S3 of the radius Q5 corresponding to the conjugacy classes of SU(2). The branes are stable due to nonzero 2-form NSNS background. In the limit

D-branes in the WZW model

It is stated in the literature that D-branes in the WZW-model associated with the gluing condition J = - \bar{J} along the boundary correspond to branes filling out the whole group volume. We show

D-branes in AdS_3xS^3xS^3xS^1

We analyse the possible D-brane configurations in an AdS_3xS^3xS^3xS^1 background with a NS-NS B field, by using the boundary state formalism. We study their geometry and we determine the fraction of
