Spaces and Black Holes

چکیده
Starting from the recent classification of quotients of Freund– Rubin backgrounds in string theory of the type AdS p+1 × S q by one-parameter subgroups of isometries, we investigate the physical interpretation of the associated quotients by discrete cyclic subgroups. We establish which quotients have well-behaved causal structures, and of those containing closed timelike curves, which have interpretations as black holes. We explain the relation to previous investigations of quotients of asymptotically flat spacetimes and plane waves, of black holes in AdS and of Gödel-type universes.

Moduli Spaces for Four - and Five - Dimensional Black Holes
We propose a universal expression for the moduli metric of a class of four-and five-dimensional black holes which preserve at least four supersymmetries. These include the black holes that are associated with various intersecting branes in ten and eleven dimensions, the electrically charged black holes of N=2 D=5 and N=2 D=4 supergravities with any number of vector multiplets, and dyonic black ...
متن کاملCardy-Verlinde Formula and Thermodynamics of Black Holes in de Sitter Spaces
We continue the study of thermodynamics of black holes in de Sitter spaces. In a previous paper (hep-th/0111093), we have shown that the entropy of cosmological horizon in the Schwarzschild-de Sitter solutions and topological de Sitter solutions can be expressed in a form of the Cardy-Verlinde formula, if one adopts the prescription to compute the gravitational mass from data at early or late t...
متن کاملLarge rotating AdS black holes from fluid mechanics
We use the AdS/CFT correspondence to argue that large rotating black holes in global AdSD spaces are dual to stationary solutions of the relativistic NavierStokes equations on SD−2. Reading off the equation of state of this fluid from the thermodynamics of non-rotating black holes, we proceed to construct the nonlinear spinning solutions of fluid mechanics that are dual to rotating black holes....
متن کاملBlack Holes and Wormholes in 2+1 Dimensions∗
Vacuum Einstein theory in three spacetime dimensions is locally trivial, but admits many solutions that are globally different, particularly if there is a negative cosmological constant. The classical theory of such locally “anti-de Sitter” spaces is treated in an elementary way, using visualizable models. Among the objects discussed are black holes, spaces with multiple black holes, their hori...
متن کاملLogarithmic corrections to the Bekenstein-Hawking entropy for five-dimensional black holes and de Sitter spaces
We calculate corrections to the Bekenstein-Hawking entropy formula for the five-dimensional topological AdS (TAdS)-black holes and topological de Sitter (TdS) spaces due to thermal fluctuations. We can derive all thermal properties of the TdS spaces from those of the TAdS black holes by replacing k by −k. Also we obtain the same correction to the Cardy-Verlinde formula for TAdS and TdS cases in...
