Some remarks on anti-de Sitter D-branes

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 rôle of the spectral flow in this context.
