Abstract
D-branes in curved backgrounds can be treated with techniques of boundary: conformal field theory. We discuss the influence of scalar condensates on s uch branes, i.e. perturbations of boundary conditions by marginal boundary operators. A general criterion is presented that guarantees a boundary pert urbation to be truly marginal in ail orders of perturbation theory. Our res ults on boundary deformations have several interesting applications which a re sketched at the end of this note.
