The role of locality in perturbation theory

The page collects material related to

on renormalization of quantum field theory compatible with causal locality. The approach came to be known as causal perturbation theory (see there for more). Its generalization to quantum field theory on curved spacetimes is known as locally covariant perturbative quantum field theory.

This is based on earlier work in

Hence one speaks of the Stückelberg-Bogoliubov-Epstein-Glaser method of renormalization, for instance in
