Osterwalder-Schrader Axioms

Definition: The Osterwalder–Schrader theorem states conditions that correlation functions on Euclidean spacetime have to satisfy to be equivalent to the correlation functions of a Wightman QFT on Minkowski spacetime.

  • It guides us how to relate collection functions calculated in flat spacetimes with Euclidean and Lorentzian signatures. Unfortunately, nothing like this is known when GR is involved, meaning with dynamical spacetime.
