Quantum Field Theory in Gravitational Background
The first step to combine Quantum Field Theory and Gravitational Theory is to ignore the influence of the quantum field on the gravitation but to consider the gravitational field as fixed and thus study quantum field theory, on a manifold. First steps in this direction are already made in Ref. 1. Interest has increased when thermal radiation of a black hole was predicted.
