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…
Generalized de Sitter solution in multidimensional cosmology with static internal spaces
A. Zhuk
A multidimensional cosmological model with space-time consisting of n (n>1) Einstein spaces M_i is investigated in the presence of a cosmological constant Lambda and a homogeneous…
Restrictions on dilatonic brane-world models
A. Zhuk
We consider dilatonic brane-world models with a non-minimal coupling between a dilaton and usual matter on a brane. We demonstrate that variation of the fundamental constants on th…
