Static near-horizon geometries in five dimensions
We consider the classification of static near-horizon geometries of stationary extremal (not necessarily BPS) black hole solutions of five dimensional Einstein-Maxwell theory coupled to a Chern-Simons term with coupling ξ (with ξ = 1 corresponding to supergravity). Assuming the black holes have two rotational symmetries, we show that their near-horizon geometries are either the direct product A...
متن کاملD-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 on a talk given at the Strings’01 conference in Mumbay. Unité mixte du CNRS et de l’Ecole Normale Supérieure, UMR 8549.
متن کاملClassification of Near-Horizon Geometries of Extremal Black Holes
Any spacetime containing a degenerate Killing horizon, such as an extremal black hole, possesses a well-defined notion of a near-horizon geometry. We review such near-horizon geometry solutions in a variety of dimensions and theories in a unified manner. We discuss various general results including horizon topology and near-horizon symmetry enhancement. We also discuss the status of the classif...
متن کاملNear-horizon geometries of supersymmetric AdS5 black holes
We provide a classification of near-horizon geometries of supersymmetric, asymptotically antide Sitter, black holes of five-dimensional U(1)-gauged supergravity which admit two rotational symmetries. We find three possibilities: a topologically spherical horizon, an S1×S2 horizon and a toroidal horizon. The near-horizon geometry of the topologically spherical case turns out to be that of the mo...
متن کاملSupermembranes in Curved Superspace and Near-horizon Geometries
We give a description of supermembranes in nontrivial target-space geometries. A special class are the AdS4 ×S7 and AdS7 ×S4 spaces that have the maximal number of 32 supersymmetries. Lecture presented at the 22-nd Johns Hopkins Workshop, Novelties in String Theory, Göteborg, August 20-22, 1998.
