Exact Results in Quantum Theory

The principle of local covariance was originally proposed in the context of quantum field theory on generic spacetime. Later on it turned out that it can also be used to formulate the requirement of background independence in the perturbative approach to quantum gravity. The idea to formulate gravity in the framework of locally covariant field theory was already applied on the classical level and the perspectives for quantization are very promising. In this talk I will present the recent results in this research area and outline the program for future studies.
