Curvaton reheating in tachyonic braneworld inflation
Cuauhtemoc Campuzano, Sergio del Campo, Ramon Herrera
The curvaton reheating in a tachyonic braneworld inflationary universe model with an exponential potential is studied. We have found that the energy density in the kinetic epoch, h…
Closed inflationary universe models in Braneworld Cosmology
Sergio del Campo, Ramon Herrera, Joel Saavedra
In this article we study closed inflationary universe models proposed by Linde in a brane world cosmological context. In this scenario we determine and characterize the existence o…
Open inflationary universes in a brane world cosmology
Sergio del Campo, Ramon Herrera, Joel Saavedra
In this paper, we study a type of one-field model for open inflationary universe models in the context of the brane world models. In the scenario of a one-bubble universe model, we…
A causal model for a closed universe
M. Cataldo, S. del Campo, P. Minning +1
We study a closed model of a universe filled with viscous fluid and quintessence matter components. The dynamical equations imply that the universe might look like an accelerated f…
Relationship between (2+1) and 3+1)--Friedmann--Robertson--Walker cosmologies
A. Garcia, M. Cataldo, S. del Campo
In this work we establish the correspondence between solutions to the Friedmann--Robertson--Walker cosmologies for perfect fluid and scalar field sources, where both ones fulfill s…
Supergravity with cosmological constant and the AdS group
P. Salgado, S. del Campo, M. Cataldo
It is shown that the supersymmetric extension of the Stelle-West formalism permits the construction of an action for -dimensional N=1 supergravity with cosmological constant…
