Electrovacuum Nearhorizon Geometries in Four and Five Dimensions
"... Associated to every stationary extremal black hole is a unique nearhorizon geometry, itself a solution of the field equations. These latter spacetimes are more tractable to analyze and most importantly, retain properties of the original black hole which are intrinsic to the event horizon. After rev ..."

Static nearhorizon geometries in five dimensions
, 907
"... We consider the classification of static nearhorizon geometries of stationary extremal (not necessarily BPS) black hole solutions of five dimensional EinsteinMaxwell theory coupled to a ChernSimons term with coupling ξ (with ξ = 1 corresponding to supergravity). Assuming the black holes have two ..."

THE NEARHORIZON GEOMETRY OF DILATONAXION BLACK HOLES
, 2001
"... Static black holes of dilatonaxion gravity become singular in the extreme limit, which prevents a direct determination of their nearhorizon geometry. This is addressed by first taking the nearhorizon limit of extreme rotating NUTless black holes, and then going to the static limit. The resulting ..."

Near horizon geometry and black holes in four dimensions
 Nucl. Phys. B528
, 1998
"... A large class of extremal and nearextremal four dimensional black holes in Mtheory feature near horizon geometries that contain three dimensional asymptotically antide Sitter spaces. Globally, these geometries are derived from AdS3 by discrete identifications. The microstates of such black holes ..."

Dbranes in some nearhorizon geometries
, 2001
"... Abstract: I review some properties of Dbranes 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 N ..."

Statistical Entropy of Magnetic Black Holes from NearHorizon Geometry
, 1998
"... Fourdimensional magnetic black holes including dilaton and abelian gauge fields which are solutions of supergravity can also be obtained by dimensional reduction of the EinsteinMaxwell gravity in five dimensions. In the extremal case the fivedimensional solutions have horizon and their nearhorizo ..."

geometry is AdS3 × S 2. In the nonextremal case the nearhorizon geometry is shown to be the product of the threedimensional BañadosTeitelboimZanelli black hole and S 2. This allows to perform microscopic counting of statistical entropy of magnetic black holes. Exact agreement with the geometric
