Single-exterior Black Holes
نویسنده
چکیده
We discuss quantum properties of the single-exterior, “geon”-type black (and white) holes that are obtained from the Kruskal spacetime and the spinless Bañados-Teitelboim-Zanelli hole via a quotient construction that identifies the two exterior regions. For the four-dimensional geon, the Hartle-Hawking type state of a massless scalar field is thermal in a limited sense, but there is a discrepancy between Lorentzian and Riemannian derivations of the geon entropy. For the threedimensional geon, the state induced for a free conformal scalar field on the conformal boundary is similarly thermal in a limited sense, and the correlations in this state provide support for the holographic hypothesis in the context of asymptotically Anti-de Sitter black holes in string theory.

Multi - Black - Holes in 3 D and 4 D anti
The (single) black hole solutions of Ba~ nados, Teitelboim and Zanelli (BTZ) in 2+1 dimensional anti-de Sitter space are generalized to an arbitrary number n of such black holes. The resulting multi-black-hole (MBH) spacetime is locally isometric to anti-de Sitter space, and globally it is obtained from the latter as a quotient space by means of suitable identiications. The MBH spacetime has n ...
متن کاملMulti-black-hole geometries in (2+1)-dimensional gravity.
Generalizations of the Black Hole geometry of Bañados, Teitelboim and Zanelli (BTZ) are presented. The theory is three-dimensional vacuum Einstein theory with a negative cosmological constant. The n-black-hole solution has n asymptotically anti-de Sitter “exterior” regions that join in one “interior” region. The geometry of each exterior region is identical to that of a BTZ geometry; in particu...

متن کاملBlack holes: A physical route to the Kerr metric
As a consequence of Birkhoff’s theorem, the exterior gravitational field of a spherically symmetric star or black hole is always given by the Schwarzschild metric. In contrast, the exterior gravitational field of a rotating (axisymmetric) star differs, in general, from the Kerr metric, which describes a stationary, rotating black hole. In this paper I discuss the possibility of a quasi–stationa...
