UMDGR 96-47, gr-qc/9511022 Multi-Black-Hole Geometries in (2+1)-Dimensional Gravity

چکیده
Generalizations of the Black Hole geometry of Ba~ nados, 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 particular, each contains a black hole horizon that surrounds (as judged from that exterior) all the other horizons. The interior region acts as a closed universe containing n black holes. The initial state and its time development are discussed in some detail for the simple case when the angular momentum parameters of all the black holes vanish. A procedure to construct n black holes with angular momentum (for n 4) is also given.

Rri{96{14; Gr-qc/9606020 Black Hole Area in Brans-dicke Theory
We have shown that the dynamics of the scalar eld (x) = \G ?1 (x)" in Brans-Dicke theories of gravity makes the surface area of the black hole horizon oscillatory during its dynamical evolution. It explicitly explains why the area theorem does not hold in Brans-Dicke theory. However, we show that there exists a certain non-decreasing quantity deened on the event horizon which is proportional to...
متن کاملThe black hole and FRW geometries of non-relativistic gravity
We consider the recently proposed non-relativistic Hořava-Lifshitz four-dimensional theory of gravity. We study a particular limit of the theory which admits flat Minkowski vacuum and we discuss thoroughly the quadratic fluctuations around it. We find that there are two propagating polarizations of the metric. We then explicitly construct a spherically symmetric, asymptotically flat, black hole...
متن کاملObservables for two-dimensional black holes.
We consider the most general dilaton gravity theory in 1+1 dimensions. By suitably parametrizing the metric and scalar eld we nd a simple expression that relates the energy of a generic solution to the magnitude of the corresponding Killing vector. In theories that admit black hole solutions, this relationship leads directly to an expression for the entropy S = 2 0=G, where 0 is the value of th...

The two dimensional substructure of general relativity and gravity, and the two dimensional geometry of quantum effect by black hole are disclosed. Then the canonical quantization of the two dimensional theory of gravity is performed. It is shown that the resulting uncertainty relations can explain black hole quantum effects. A quantum gravitational length is also derived which can clarify the ...
