symmetric monoidal (∞,1)-category of spectra
Given a local action functional on fields which are sections of a suitable field bundle, perturbation theory and renormalization allow to assign to open subsets of spacetime/worldvolume the corresponding quantum BV-complexes/Beilinson-Drinfeld algebras. This assignment is canonically equipped with the structure of a factorization algebra, the factorization algebra of observables of the theory.
This formalization of algebraic quantum field theory is similar to, but a bit different from, the notion of local net of observables.
