Discussed differences between induced and effective geometries
Abstract
We study D-branes of the WZW model, and of its discrete orbifolds. Gluing the currents by group automorphisms leads to three types of D-branes: two-dimensional hyperbolic planes (), de Sitter branes (dS), or anti-de-Sitter branes (AdS). We explain that the dS branes are unphysical, because the electric field on their worldvolume is supercritical. By combining and SU(2), we exhibit a class of supersymmetric AdS three-brane worldvolumes, and consider their possible embeddings in the near-horizon region of stringy black holes. We point out the intriguing difference between the induced and the effective geometries of these D-branes, and speculate on its possible significance.
