General Covariance in Quantum Field Theory on Curved Spacetimes — •Thomas-Paul Hack — Department of Mathematics, University of Genoa

We highlight the role of general covariance in quantum field theory on curved spacetimes, and review how this principle is implemented at various steps in the perturbative construction of interacting models. We discuss conceptual and phenomenological consequences of the requirement of general covariance, which are of relevance e.g. in Cosmology.
