# Basics of inflationary cosmology

@inproceedings{Lazarides2006BasicsOI, title={Basics of inflationary cosmology}, author={George Lazarides}, year={2006} }

The early stages of the universe evolution are discussed according to the hot big bang model and the grand unified theories. The shortcomings of big bang are summarized and their resolution by inflationary cosmology is sketched. Cosmological inflation, the subsequent oscillation and decay of the inflaton field, and the resulting reheating of the universe are studied in some detail. The density perturbations produced by inflation and the temperature fluctuations of the cosmic microwave…
