1306.1058 (Romeo Brunetti et al.)

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

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.
