Comment on the Calculation of the Angular Momentum and Mass for the (Anti-) Self Dual Charged Spinning BTZ Black Hole
نویسنده
چکیده
A recent paper [M. Kamata and T. Koikawa, Phys. Lett. B353 (1995) 196.] claimed to obtain the charged version of the (2 + 1)-dimensional spinning BTZ black hole solution by assuming a (anti-) self dual condition imposed on the electric and magnetic fields. We point out that the angular momentum and mass diverge at spatial infinity and as a consequence the solution is unphysical

We generate from the static charged BTZ black hole a family of spinning charged solutions to the Einstein-Maxwell equations in 2+1 dimensions. These solutions go over, in a suitable limit, to self-dual spinning charged solutions, which are horizonless and regular, with logarithmically divergent mass and spin. To cure this divergence, we add a topological Chern-Simons term to the gauge field act...
متن کاملSpinning Black Holes in (2 + 1)-dimensional String and Dilaton Gravity
We present a new class of spinning black hole solutions in (2+1)-dimensional general relativity minimally coupled to a dilaton with potential ebφΛ. When b = 4, the corresponding spinning black hole is a solution of low energy (2 + 1)-dimensional string gravity. Apart from the limiting case of the BTZ black hole, these spinning black holes have no inner horizon and a curvature singularity only a...
متن کاملFe b 19 99 Remarks on Conserved Quantities and Entropy of BTZ Black Hole Solutions . Part I : the General Setting
The BTZ stationary black hole solution is considered and its mass and angular momentum are calculated by means of Nöther theorem. In particular, relative conserved quantities with respect to a suitably fixed background are discussed. Entropy is then computed in a geometric and macroscopic framework, so that it satisfies the first principle of thermodynamics. In order to compare this more genera...
متن کاملA Simplified Solution for Advection Dominated Accretion Flows with Outflow
The existence of outflow in the advection dominated accretion flows has been confirmed by both numerical simulations and observations. The outow models for ADAF have been investigated by several groups with a simple self similar solution. But this solution is inaccurate at the inner regions and can not explain the emitted spectrum of the flow; so, it is necessary to obtain a global solution for...

We calculate the entropy of a scalar field in a rotating black hole in 2 + 1 dimension. In the Hartle-Hawking state the entropy is proportional to the horizon area, but diverges linearly in √ h, where h is the radial cut-off. In WKB approximation the superradiant modes do not contribute to the entropy. e-mail : [email protected] e-mail : [email protected] 1 Recently, many efforts have...
