Foundations of Quantum Cosmology

This book lays the
foundations of quantum cosmology, developing classical cosmology and quantum
physics based on general principles without requiring detailed background
knowledge in these fields. Throughout the book, the discussion focuses on the
physical meaning of space-time - classical or quantum - and on the important
requirement of general covariance. Various classical models are derived from
this condition and applied to basic questions in cosmology and the physics of
black holes. The book's introduction of relevant ingredients from quantum
physics makes it possible to derive fundamental features of quantum cosmology,
to present the main approaches to quantum gravity, including string theory and
causal dynamical triangulations, and to outline some of their cosmological
implications. It is an essential guide for researchers in quantum gravity and
astrophysicists interested in fundamental aspects of cosmology.
