Randall-Sundrum limit of f(R) brane-world models
Randall-Sundrum limit brane-world models
2011/10/17
By setting some special boundary conditions in the variational principle we obtain junction conditions for the five-dimensional $f(R)$ gravity which in the Einstein limit $f(R)\rightarrow R$ transform...
De Sitter brane-world, localization of gravity, and the cosmological constant
De Sitter brane-world localization of gravity the cosmological constant
2010/12/24
Cosmological models with a de Sitter 3-brane embedded in a five-dimensional de Sitter spacetime (dS5) give rise to a finite 4D Planck mass similar to that in Randall-Sundrum (RS) brane-world models in...

In this paper we discuss the properties of the general covariant angular momentum of a five-dimensional brane-world model. Through calculating the total angular momentum of this model, we are able to ...

Is it Possible to Test Brane-World Scenarios by Observation of Quasars and Microquasars?
Brane-World Scenarios Quasars and Microquasars
2010/10/18
The aim of this work is to present a possible way to estimate observational electromagnetical clues in the spectrum of quasars and microquasars due to the presence of extra dimensions. Here we analyze...
