Exploring the dark side of the Universe in a dilatonic brane-world scenario
Mariam Bouhmadi-López
We describe the late-time acceleration of the Universe within the paradigm of the brane-world scenario. More precisely, we show how a phantom-like behaviour or a crossing of the co…
On new gravitational instantons describing creation of brane-worlds
M. Bouhmadi-Lopez, P. F. Gonzalez-Diaz, A. Zhuk
By considering 5--dimensional cosmological models with a bulk filled with a pressureless scalar field; equivalently dust matter, and a negative cosmological constant, we have found…
Topological defect brane-world models
M. Bouhmadi-Lopez, P. F. Gonzalez-Diaz, A. Zhuk
5-dimensional homogeneous and isotropic models with a bulk cosmological constant and a minimally coupled scalar field are considered. We have found that in special cases the scalar…
Comments on conformal stability of brane-world models
M. Bouhmadi-Lopez, A. Zhuk
The stability of 5-D brane-world models under conformal perturbations is investigated. The analysis is carried out in the general case and then it is applied to particular solution…
