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…
