String Theory Formulation of anti-de Sitter Black Holes
نویسنده
چکیده
It is shown that the five-dimensional anti-de Sitter black hole is a supersymmetric solution of the low-energy field equations of type IIB string theory compactified on an Einstein space. The near-horizon geometry is shown to be locally equivalent to threedimensional anti-de Sitter space (adS3). The entropy of the extreme black hole can then be computed from a knowledge of the asymptotic symmetry algebra of adS3.

Comments on Black Holes in String Theory
A very brief review is given of some of the developments leading to our current understanding of black holes in string theory. This is followed by a discussion of two possible misconceptions in this subject – one involving the stability of small black holes and the other involving scale radius duality. Finally, I describe some recent results concerning quasinormal modes of black holes in anti d...
متن کاملQuantum Properties of Topological Black Holes
We examine quantum properties of topological black holes which are asymptotically anti–de Sitter. First, massless scalar fields and Weyl spinors which propagate in the background of an anti–de Sitter black hole are considered in an exactly soluble two–dimensional toy model. The Boulware–, Unruh–, and Hartle–Hawking vacua are defined. The latter results to coincide with the Unruh vacuum due to t...
متن کاملTwo-dimensional black holes as open strings: A new realization of the ADS/CFT duality
Two-dimensional dilaton gravity on Anti-de Sitter space is shown to be dual to an open string. Neumann and Dirichlet boundary conditions for the string lead to two different realizations of the Anti-de Sitter/Conformal Field Theory correspondence. In particular, in the Dirichlet case the thermodynamical entropy of two-dimensional black holes can be exactly reproduced by counting the string stat...
متن کاملExact Three Dimensional Black Holes in String Theory
A black hole solution to three dimensional general relativity with a negative cosmological constant has recently been found. We show that a slight modification of this solution yields an exact solution to string theory. This black hole is equivalent (under duality) to the previously discussed three dimensional black string solution. Since the black string is asymptotically flat and the black ho...
