Introduction to QFT on curved spacetimes
23.4.2007, 15:00 Uhr – 16:00 Uhr

In General Relativity spacetime is described mathematically by a Lorentzian manifold. Gravitation manifests itself as the curvature of this manifold. Physical fields, such as the electromagnetic field, are defined on this manifold and have to satisfy a wave equation. We will summarize the basic analytic theory of linear wave equations on a suitable class of Lorentzian manifolds.

The aim of quantum field theory on curved spacetimes is to provide a partial unification of General Relativity with Quantum Physics where the gravitational field is left classical while the other fields are quantized. We show how to construct the quantization functors such that the Haag-Kastler axioms of a local quantum field theory are satisfied. We also construct Fock space representations and the corresponding quantum field.
