"... A groundbreaker in being an introductory text on quantum field theory in gravitational backgrounds, intended for undergraduate and beginning graduate students."
Lewis H. Ryder, Mathematical Reviews
"The treatment is clear throughout and the mathematical manipulations straightforward. This book is to be greatly recommended to anyone with an interest in contemporary theoretical cosmology; it is a most valuable contribution to the literature on the early universe."
This book, first published in 2007, is an introductory textbook on quantum field theory in gravitational backgrounds for undergraduate and beginning graduate students in the fields of theoretical astrophysics, cosmology, particle physics, and string theory. It is self-contained and assumes only a basic knowledge of general relativity, and includes exercises with detailed solutions.
