This book accompanies another book by the same authors, and presents the theory of the evolution of density perturbations and relic gravity waves, theory of cosmological inflation and post-inflationary reheating. Written in a pedagogical style, the main chapters give a detailed account of the established theory, with derivation of formulas. Being self-contained, it is a useful textbook for advanced undergraduate students and graduate students. Essential materials from General Relativity, theory of Gaussian random fields and quantum field theory are collected in the appendices. The more advanced topics are approached similarly in a pedagogical way. These parts may serve as a detailed introduction to current research.Shipping Notes

Perfect polo shirt
I love these shirts for the way they feel on my sensitive skin. The color adds a bit of interest which has been commented
I like these shirts very much and have bought one of almost every color, mostly short sleeved, but some long. They suit my sensitive skin which I've acquired in old age. Probably the only thing I wear which has ever been commented on.

Excellent Polo Shirt
In the past weeks I bought one for my dad and my mom was in love with the fabric, soft and easy to wash. After that we got almost all the colors that they have.
I highly recommended it.
Thanks
