內容簡介
Quantum gravity is one of the major open problems in theoretical
physics. The loop and spinfoam approach, presented in this book, is
a leading research program in the field. Emphasis is given to
conceptual and foundational issues raised by quantum gravity,
especially on the nature of space and time. This text is intended
for researchers working in quantum gravity and, in particular,
graduate students entering the field. It will also appeal to
philosophers and scientists interested in the general issue of the
nature of space and time.
