"Quantum Gravitation" approaches the subject from the point of
view of Feynman path integrals, which provide a manifestly
covariant approach in which fundamental quantum aspects of the
theory such as radiative corrections and the renormalization group
can be systematically and consistently addressed. It is shown that
the path integral method is suitable for both perturbative as well
as non-perturbative studies, and is already known to offer a
framework for the theoretical investigation of non-Abelian gauge
theories, the basis for three of the four known fundamental forces
in nature. The book thus provides a coherent outline of the present
status of the theory gravity based on Feynman's formulation, with
an emphasis on quantitative results.
Topics are organized in such a way that the correspondence to
similar methods and results in modern gauge theories becomes
apparent. Covariant perturbation theory are developed using the
full machinery of Feynman rules, gauge fixing, background methods
and ghosts. The renormalization group for gravity and the existence
of non-trivial ultraviolet fixed points are investigated, stressing
a close correspondence with well understood statistical field
theory models. The final chapter addresses contemporary issues in
quantum cosmology such as scale dependent gravitational constants
and quantum effects in the early universe.
