QFT on curved spacetimes: axiomatic framework and examples

Understand

In this overview article we present a formalism suitable for constructing models of QFT's on curved spacetimes.

• The leading principle is the emphasis on local properties.
• It turns out that this requires a reformulation of the standard QFT framework which also yields a new perspective for the theories on Minkowski space.
• The aim of the present work is to provide an introduction into the framework, which should be accessible for both mathematical physicists and mathematicians.
