Geodesic motion in the neighbourhood of submanifolds embedded in warped product spaces
Fabio Dahia, Carlos Romero, Lucio F. P. Silva +1
We study the classical geodesic motions of nonzero rest mass test particles and photons in (3+1+n)- dimensional warped product spaces. An important feature of these spaces is that…
Modified Brans-Dicke theory of gravity from five-dimensional vacuum
Jose Edgar Madriz Aguilar, Carlos Romero, Adriano Barros
We investigate, in the context of five-dimensional (5D) Brans-Dicke theory of gravity, the idea that macroscopic matter configurations can be generated from pure vacuum in five dim…
The Schwarzschild-de Sitter solution in five-dimensional general relativity briefly revisited
J. B. Fonseca-Neto, C. Romero
We briefly revisit the Schwarzschild-de Sitter solution in the context of five-dimensional general relativity. We obtain a class of five-dimensional solutions of Einstein vacuum fi…
Warped product spaces and geodesic motion in the neighbourhood of hypersurfaces
F. Dahia, C. Romero, L. F. P. Silva +1
We study the classical geodesic motions of nonzero rest mass test particles and photons in five-dimensional warped product spaces. We show that it is possible to obtain a general p…
Confinement and stability of the motion of test particles in thick branes
F. Dahia, C. Romero
We consider the motion of test particles in a thick brane version of Randall-Sundrum type II model. It is known that gravity alone cannot explain the confinement of test particles…
AdS and stabilized extra dimensions in multidimensional gravitational models with nonlinear scalar curvature terms 1/R and R^4
Uwe Guenther, Alexander Zhuk, Valdir Bezerra +1
We study multidimensional gravitational models with scalar curvature nonlinearities of the type 1/R and R^4. It is assumed that the corresponding higher dimensional spacetime manif…
