Ekpyrotic and Cyclic Cosmology
by Jean-Luc Lehners
Publisher: arXiv 2009
Number of pages: 79
Description:
Ekpyrotic and cyclic cosmologies provide theories of the very early and of the very late universe. In these models, the big bang is described as a collision of branes - and thus the big bang is not the beginning of time. Before the big bang, there is an ekpyrotic phase with equation of state w=P/rho >> 1 during which the universe slowly contracts.

Introduction to Early Universe Cosmology
by Robert H. Brandenberger - arXiv
This text covers the theory of cosmological perturbations, which describes the generation of inhomogeneities in the early universe and their evolution until the current time. The theory is applied to three classes of models of the early universe.
