چکیده

It has been shown in the presence of the cosmological constant any solution of the Einstein field equations that asymptotically approaches to the static desitter metric does not correspond to an observer of a comoving frame but it should approach to the deSitter metric in the form of Robertson Walker metric (gr-qc/9812092) . For the case of Schwarzschild deSitter its proper form had been derived (gr-qc/9902009) . Here we are going to present our derivations for a proper form of the Kerr-deSitter metric. This has been done by considering the stationary axially-symmetric spacetime in which motion of particle is integrable. That is the Hamilton-Jacobi and Klein-Gordon equations are separable. As in the Schwarzschild deSitter case it does not possess any event horizon without imposing any additional conditions .Its intrinsic singularity and surfaces of infinite redshifts remains the same as common Kerr solutions.

Quantum stress tensor in the three-dimensional black hole.

The quantum stress tensor < Tμν > is calculated in the 2+1 dimensional black hole found by Banados, Teitelboim, and Zanelli. The Greens function, from which < Tμν > is derived, is obtained by the method of images. For the non-rotating black hole, it is shown that < Tμν > is finite on the event horizon, but diverges at the singularity. For the rotating solution, the stress tensor is finite at th...

〈φ2〉 in the Spacetime of a Cylindrical Black Hole

The renormalised value of 〈φ2〉 is calculated for a massless, conformally coupled scalar field in the Hartle-Hawking vacuum state. This calculation is a first step towards the calculation of the gravitational back reaction of the field in a black cosmic string spacetime which is asymptotically anti-DeSitter and posesses a non constant dilaton field. It is found that the field is divergence free ...

The Uniqueness Theorem for Rotating Black Hole Solutions of Self-gravitating Harmonic Mappings

We consider rotating black hole configurations of self-gravitating maps from spacetime into arbitrary Riemannian manifolds. We first establish the integrability conditions for the Killing fields generating the stationary and the axisymmetric isometry (circularity theorem). Restricting ourselves to mappings with harmonic action, we subsequently prove that the only stationary and axisymmetric, as...

فضا زمان های در حال تحول با فشار شعاعی خالص

  In this study time-dependent and spherically symmetric solutions of the Einstein field equations in an anisotropic background with a purely radial tension are presented. There exist three classes of solutions,1) An open spacetime with a wormhole at its center. 2) A conical spacetime. 3) A closed spacetime. These inhomogeneous solutions are reduced to FRW spacetimes in matter-dominated era, as...

Hawking radiation of Kerr-Newman-de Sitter black hole

We extend the classical Damour-Ruffini method and discuss Hawking radiation in KerrNewman-de Sitter(KNdS) black hole. Under the condition that the total energy, angular momentum and charge of spacetime are conserved, taking the reaction of the radiation of the particle to the spacetime and the relation between the black hole event horizon and the cosmological horizon into consideration, we deri...
