Quantum gravity from the point of view of locally covariant quantum
field theory    [PDF]

Romeo Brunetti, Klaus Fredenhagen, Katarzyna Rejzner

We construct perturbative quantum gravity in a generally covariant way. In particular our construction is background independent. It is based on the locally covariant approach to quantum field theory and the renormalized Batalin-Vilkovisky formalism. We do not touch the problem of nonrenormalizability and interpret the theory as an effective theory at large length scales.
