Summary Aside from the obvious statement that it should be a theory capable of unifying general relativity and quantum field theory, not much is known about the true nature of quantum gravity
Because it is an exciting area of research, there are many new ideas about quantum gravity, but they often diverge to such an incredible degree that it seems impossible to decide which of the many possible directions the ongoing developments should be pursued
The division of this text into two overlapping parts reflects the duality between the physical vision and the mathematical construction of quantum gravity research. The former is represented by tutorial reviews on non-commutative geometry, on space-time discretization and renormalization, and on gauge field path integrals. The latter contains lectures on cohomology, on stochastic geometry and on mathematical tools for the effective action in quantum gravity
This book will benefit everyone working in or entering the field of quantum gravity research. --Book Jacket
