Microscopic origin of the Bekenstein-Hawking entropy
Abstract The Bekenstein-Hawking area-entropy relation S BH = A 4 is derived for a class of five-dimensional extremal black holes in string theory by counting the degeneracy of BPS solition boundExpand
Superstrings with Torsion
Abstract The conditions for spacetime supersymmetry of the heterotic superstring in backgrounds with arbitrary metric, torsion, Yang-Mills and dilaton expectation values are determined using theExpand
Black hole entropy in M theory
Extremal black holes in M-theory compactification on M × S1 are microscopically represented by fivebranes wrapping P × S1, where M is a Calabi-Yau threefold and P is a four-cycle in M. AdditionalExpand
Black strings and p-branes
It is shown that low-energy string theory admits a variety of solutions with the structure of an extended object surrounded by an event horizon. In particular there is a family of black stringExpand
Kerr/CFT Correspondence
Quantum gravity in the region very near the horizon of an extreme Kerr black hole (whose angular momentum and mass are related by J=GM{sup 2}) is considered. It is shown that consistent boundaryExpand
Chiral gravity in three dimensions
Three dimensional Einstein gravity with negative cosmological constant ?1/?2 deformed by a gravitational Chern-Simons action with coefficient 1/? is studied in an asymptotically AdS3 spacetime. It isExpand
Black hole entropy from near-horizon microstates
Black holes whose near-horizon geometries are locally, but not necessarily globally, AdS3 (three-dimensional anti-de Sitter space) are considered. Using the fact that quantum gravity on AdS3 is aExpand
Vacuum configurations for superstrings
We study candidate vacuum configurations in ten-dimensional O(32) and E 8 × E 8 supergravity and superstring theory that have unbroken N = 1 supersymmetry in four dimensions. This condition permitsExpand
The dS/CFT correspondence
A holographic duality is proposed relating quantum gravity on dSD (D-dimensional de Sitter space) to conformal field theory on a single SD−1 ((D-1)-sphere), in which bulk de Sitter correlators withExpand
AdS3 black holes and a stringy exclusion principle
The duality relating near-horizon microstates of black holes obtained as orbifolds of a subset of AdS3 to the states of a conformal field theory is analyzed in detail. The SL(2,R)L?SL(2,R)R invariantExpand
