de Sitter Thermodynamics: A glimpse into non equilibrium
Rodrigo Aros
In this article is shown that the thermodynamical evolution of a Schwarzschild de Sitter space is the evaporation of its black hole. The result is extended in higher dimensions to…
Counting the negative eigenvalues of the thermalon in three dimensions
Rodrigo Aros, Andres Gomberoff, Alejandra Montecinos
Some years ago it was shown that the cosmological constant may be reduced by thermal production of membranes that, after nucleation, collapse into a black hole. The probability of…
Compactification in first order gravity
Rodrigo Aros, Mauricio Romo, Nelson Zamorano
The Kaluza-Klein compactification process is applied in five dimensions to CS gravity, for the anti-de Sitter and Poincaré groups, using the first order formalism. In this context…
Algebraic cycles on Severi-Brauer schemes of prime degree over a curve
Cristian D. Gonzalez-Aviles
Let be a perfect field and let be a prime number different from the characteristic of . Let be a smooth, projective and geometrically integral -curve and let …
Inflation, Reheating and Dark Matter
Victor H. Cardenas
In a recent paper, Liddle and Urena-Lopez suggested that to have a unified model of inflation and dark matter is imperative to have a proper reheating process where part of the inf…
