Black Holes in de Sitter Space: Masses, Energies and Entropy Bounds
Alejandro Corichi, Andres Gomberoff
In this paper we consider spacetimes in vacuum general relativity --possibly coupled to a scalar field-- with a positive cosmological constant . We employ the Isolated Horizons…
Thermal Decay of the Cosmological Constant into Black Holes
Andres Gomberoff, Marc Henneaux, Claudio Teitelboim +1
We show that the cosmological constant may be reduced by thermal production of membranes by the cosmological horizon, analogous to a particle ``going over the top of the potential…
de Sitter Black Holes with Either of the Two Horizons as a Boundary
Andres Gomberoff, Claudio Teitelboim
The action and the thermodynamics of a rotating black hole in the presence of a positive cosmological constant are analyzed. Since there is no spatial infinity, one must bring in,…
Quantization of the Chern-Simons Coupling Constant
Xavier Bekaert, Andres Gomberoff
We investigate the quantum consistency of p-form Maxwell-Chern-Simons electrodynamics in 3p+2 spacetime dimensions (for p odd). These are the dimensions where the Chern--Simons ter…
