چکیده
state O.B.Zaslavskii Department of Physics, Kharkov State University, Svobody Sq.4, Kharkov 310077, Ukraine E-mail: [email protected] Dilaton black holes with a pure electric charge are considered in the frame work of a grand canonical ensemble near the extreme state. It is shown that there exists such a subset of boundary data that the Hawking temperature smoothly goes to zero to an infinite value of a horizon radius but the horizon area and entropy are finite and differ from zero. In string theory the existence of a horizon in the extreme limit is due to the finiteness of a system only. 04.70Dy, 97.60Lf, 04.20 Jb

Phases of R-charged Black Holes, Spinning Branes and Strongly Coupled Gauge Theories
We study the thermodynamic stability of charged black holes in gauged supergravity theories in D = 5, D = 4 and D = 7. We find explicitly the location of the Hawking-Page phase transition between charged black holes and the pure anti-de Sitter space-time, both in the grand-canonical ensemble, where electric potentials are held fixed, and in the canonical ensemble, where total charges are held f...

Different geometrical and topological properties have been shown for two kinds of extreme Reissner-Nordström-anti-de Sitter black holes. The relationship between the geometrical properties and the intrinsic thermodynamical properties has been made explicit.

متن کامل0 M ar 1 99 9 Thermodynamics of charged anti - de Sitter black holes in canonical ensemble
As in the grand canonical treatment of Reissner-Nordström black holes in anti-de Sitter spacetime, the canonical ensemble formulation also shows that non-extremal black holes tend to have lower action than extremal ones. However, some small non-extremal black holes have higher action, leading to the possibility of transitions between non-extremal and extremal black holes.
متن کاملSupersymmetry as a cosmic censor.
In supersymmetric theories the mass of any state is bounded below by the values of some of its charges. The corresponding bounds in the case of Schwarzschild (M & 0 ) and Reissner-Nordstrom (M & ~q~) black holes are known to coincide with the requirement that naked singularities be absent. Here we investigate [U(1)j charged dilaton black holes in this context. The extreme solutions are shown to...
متن کاملSchwarzschild black hole as a grand canonical ensemble
For long black holes have been considered as endowed with a definite temperature. Yet when the Schwarzschild black hole is treated as a canonical ensemble three problems arise: incompatibility with the Hawking radiation, divergence of the partition function, and a formally negative mean-square fluctuation of the energy. We solve all three problems by considering the Schwarzschild black hole as ...
