The purpose of this review is to discuss recent developments occurring at the interface of cosmology with string and M theory. We begin with a short review of 1980s string cosmology and the Brandenberger–Vafa mechanism for explaining space–time dimensionality. It is shown how this scenario has been modified to include the effects of p-brane gases in the early universe. We then introduce the Pre-Big-Bang scenario (PBB), Hořava–Witten heterotic M theory and the work of Lukas, Ovrut and Waldram… 

Loitering phase in brane gas cosmology

Brane Gas Cosmology and Loitering

In Brane Gas Cosmology (BGC) the initial state of the universe is taken to be small, dense and hot, with all fundamental degrees of freedom near thermal equilibrium. This starting point is in close

Brane world cosmology

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 Randall–Sundrum brane

Towards a stringy resolution of the cosmological singularity

We study cosmological solutions to the low-energy effective action of heterotic string theory including possible leading order $\alpha'$ corrections and a potential for the dilaton. We consider the

Cosmology and brane worlds: a review

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 hypersurface (a so-called

On the Spectrum of Fluctuations in an Effective Field Theory of the Ekpyrotic Universe

We consider the four-dimensional effective field theory which has been used in previous studies of perturbations in the Ekpyrotic Universe, and discuss the spectrum of cosmological fluctuations

Brane inflation and reheating

We study inflation and reheating in a brane world model derived from type IIA string theory. This particular set-up is based on a model of string mediated supersymmetry breaking. The inflaton is one

Topics in stringy cosmology

This thesis is composed of two distinct research topics. The first topic concerns RandallSundrum cosmological models, in particular their isotropization properties at early times. We first study the

Lectures on string/brane cosmology

An overview of some cosmological aspects of string theory is presented. Recent developments are emphasized, especially the attempts to derive inflation or alternatives to inflation from the dynamics

Cosmology and Heterotic M--Theory in Five-Dimensions

In these lectures, we present cosmological vacuum solutions of Horava-Witten theory and discuss their physical properties. We begin by deriving the five-dimensional effective action of strongly

Imaginative Cosmology

. We review 1 a few off-the-beaten-track ideas in cosmology. They solve a variety of fundamental problems; also they are fun. We start with a description of non-singular dilaton cosmology. In these

Stringy world branes and exponential hierarchies

It is argued that an assumption that is needed in the RS explanation of the hierarchy is hard to satisfy in the string theory context.

Bulk fields in the Randall-Sundrum compactification scenario

Recently, Randall and Sundrum proposed a solution to the hierarchy problem where the background spacetime is five dimensional. There are two 3-branes, and the mass scale for fields that propagate on

p -brane cosmology and phases of Brans-Dicke theory with matter

We study the effect of the solitonic degrees of freedom in string cosmology following the line of Rama. The gas of solitonic p-brane is treated as a perfect fluid in a Brans-Dicke type theory. In

FROM p-BRANES TO COSMOLOGY

We study the relationship between static p-brane solitons and cosmological solutions of string theory or M theory. We discuss two different ways in which extremal p-branes can be generalized to
