Abstract

This is a short survey of results contained in [1]. We study the influence of gravitation on quantum field theory, insofar, that gravity is considered as background field, changing Minkowski space into a general Riemannian manifold. Considerations in this respect were started in [2]. The propagator for the Weyl algebra was found in [3]. Interest in the model increased when in [4] thermal radiation was predicted as consequence of a reasonable state in a Schwarzschild metric (the choice of this state was based on arguments on the time evolution of the black hole). We will restrict the allowed physical states by local conditions and deduce their consequences in the tangent space. They determine already the temperature of the black hole.
