The Haag-Kastler Axioms for the $P (\varphi)_2$ Model on the De Sitter Space Jaekel, Christian


(Joint work with Jens Mund)

We establish the Haag-Kastler axioms for a class of interacting quantum field theories on the twodimensional de Sitter space, which satisfy finite speed of light. The $P (\varphi)_2$ model constructed by Barata, Jäkel & Mund, describing massive scalar bosons with polynomial interactions, provides an example.
