Locally covariant quantum field theory
arXiv:hep-th/0403007
Abstract
The principle of local covariance which was recently introduced admits a generally covariant formulation of quantum field theory. It allows a discussion of structural properties of quantum field theory as well as the perturbative construction of renormalized interacting models on generic curved backgrounds and opens in principle the way towards a background independent perturbative quantization of gravity.
