Leonard Parker is a Distinguished Professor of physics and director of the Center for Gravitation and Cosmology at the University of Wisconsin-Milwaukee. He is basically the founder of the study of quantum field theory in curved space-time. His has work formed the basis of research by hundreds of physicists worldwide including being cited by Stephen Hawking in his discover the creation of particles by black holes.

David Toms (Ph.D. University of Toronto) is a member of the faculty in Mathematical Physics at the University of Newcastle. He has published numerous papers in Quantum field theory, General relativity, Quantum gravity, Bose-Einstein condensation, and Statistical mechanics.

This book, positioned at the graduate level requires considerable background in classical general relativity, basic quantum field theory, and the associated mathematics. It is mathematically rigorous and could be used for a one or two semester course or by the individual researcher.
