A review of the geometry and density of the universe, with a focus on inflationary models.

The following pages present a discussion of the role the cosmological constant plays in modern cosmology. They are designed to offer an overview of how the cosmological constant alters standard cosmology, and to discuss whether a non-zero cosmological constant exists today.

A thesis (in PDF format) which studies the possible topologies of the universe and their physical implications.

A review of how the understanding of our Universe has evolved

The aim of this lecture is to highlight two areas of recent progress in inflationary cosmology, namely reheating and the quantum theory of cosmological perturbations.

A very basic overview of cosmology

A lecture on aspects of superstring theory and cosmology.

Progress in early Universe cosmology, including strings, extra dimensions, inflation, phase transitions, and baryogenesis, is reviewed.

A short review of recent results on exact solutions in multidimensional cosmology

A review of modern cosmology theories by P. James E. Peebles
