These notes give an introductory review on brane cosmology. This subject deals with the cosmological behaviour of a brane-universe, i.e. a three-dimensional space, where ordinary matter is confined, embedded in a higher dimensional spacetime. In the tractable case of a five-dimensional bulk spacetime, the brane (modified) Friedmann equation is discussed in detail, and various other aspects are presented, such as cosmological perturbations, bulk scalar fields and systems with several branes.

Cosmological solutions in the brane-bulk system
Abstract.In this work we find cosmological solutions in the brane-bulk system starting from a 5D line element which is a simple extension, for cosmological applications, of the pioneering
Inhomogeneous exact solution in brane gravity and its applications
Considering an inhomogeneous brane embedded in a five dimensional constant curvature bulk, we find the non-static and spherically symmetric exact solutions of the Einstein equations on the brane.
Brane cosmology with an anisotropic bulk
In the context of brane cosmology, a scenario where our universe is a 3+1-dimensional surface (the ``brane'') embedded in a five-dimensional spacetime (the ``bulk''), we study geometries for which
A Cosmological Model of Holographic Brane Gravity
A cosmological scenario with two branes (A and B) moving in a 5-dimensional bulk is considered. As in the case of ecpyrotic and born-again braneworld models it is possible that the branes collide.
Late time behaviour of cosmological perturbations in a single-brane model
We present solutions for the late time evolution of cosmological tensor and scalar perturbations in a single-Randall–Sundrum-brane world model. Assuming that the bulk is anti-de Sitter spacetime, the
de Sitter branes with a bulk scalar
We propose new brane world models arising from a scalar field in the bulk. In these examples, the induced on-brane line element is de Sitter (or anti de Sitter) and the bulk (five dimensional)
Brane-world cosmology and varying G
We consider a brane-world cosmological model coupled to a bulk scalar field. Since the brane tension turns out to be proportional to Newton's coupling G, in such a model a time variation of G
Inflation in anisotropic brane universe using tachyon field
Cosmological solution to the gravitational field equations in the generalized Randall–Sundrum model for an anisotropic brane with Bianchi-I geometry and perfect fluid as matter sources has been


Brane-World Cosmology, Bulk Scalars and Perturbations
We investigate aspects of cosmology in brane world theories with a bulk scalar field. We concentrate on a recent model motivated from supergravity in singular spaces. After discussing the background
Brane cosmological perturbations
We address the question of cosmological perturbations in the context of brane cosmology, where our Universe is a three-brane where matter is confined, whereas gravity lives in higher-dimensional
Evolution of cosmological perturbations in a brane-universe.
In the present Letter, the impact of the existence of extra dimensions on cosmology, in particular, on the evolution of cosmological perturbations is analyzed.
Cosmological Perturbations in Brane-World Theories: Formalism
We develop a gauge-invariant formalism to describe metric perturbations in five-dimensional brane-world theories. In particular, this formalism applies to models originating from heterotic M theory.
Cosmological equations for a thick brane
Generalized Friedmann equations governing the cosmological evolution inside a thick brane embedded in a five-dimensional Anti-de Sitter spacetime are derived. These equations are written in terms of
The cosmological constant problem from a brane-world perspective
We point out several subtleties arising in brane-world scenarios of cosmological constant cancellation. We show that solutions with curvature singularities are inconsistent, unless the contribution
Cosmological brane world solutions with bulk scalar fields
Cosmological brane world solutions are found for five-dimensional bulk spacetimes with a scalar field. A supergravity inspired method for obtaining static solutions is combined with a method for
Gauge invariant cosmological perturbation theory for braneworlds
We derive the gauge invariant perturbation equations for a 5-dimensional bulk spacetime in the presence of a brane. The equations are derived in full generality, without specifying a particular
Brane world cosmology
A simple model of the brane-world cosmology has been proposed, which is characterized by four parameters, namely, the bulk cosmological constant, the spatial curvature of the universe, the radiation
