The theory of inflation with single and multiple fields is reviewed paying particular attention
to the dynamics of adiabatic and entropy/isocurvature perturbations which provide the …

The observable universe could be a 1+ 3-surface (the “brane”) embedded in a 1+ 3+ d-
dimensional spacetime (the “bulk”), with Standard Model particles and fields trapped on the …

We discuss the cosmology of a 3-brane embedded in a 5D bulk space–time with a
cosmological constant when an intrinsic curvature Ricci scalar is included in the brane …

We study gravity in backgrounds that are smooth generalizations of the Randall–Sundrum
model, with and without scalar fields. These generalizations include three-branes in higher …

We show that in four or more spacetime dimensions, the Einstein equations for gravitational
perturbations of maximally symmetric vacuum black holes can be reduced to a single …

Cosmological consequences of the brane world scenario are reviewed in a pedagogical
manner. According to the brane world idea, the standard model particles are confined on a …

We extend the formulation for perturbations of maximally symmetric black holes in higher
dimensions developed by the present authors in a previous paper to a charged black hole …

These notes give an introductory review on brane cosmology. This subject deals with the
cosmological behaviour of a brane-universe, ie a three-dimensional space, where ordinary …

Abstract In Randall-Sundrum-type brane-world cosmologies, the dynamical equations on
the three-brane differ from the general relativity equations by terms that carry the effects of …

Recent developments in the physics of extra dimensions have opened up new avenues to
test such theories. We review cosmological aspects of brane world scenarios such as the …
