Summary
Assuming that the energy-momentum spectrum is contained in the closed forward light-cone, we prove necessary and sufficient conditions for conservation of translationally covariant and of conformal currents. These theorems can be interpreted as generalizations of Coleman's theorem.
Riassunto
Supponendo che lo spettro dell'energia-impulso sia contenuto nel cono di luce anteriore chiuso, si dimostrano le condizioni necessarie e sufficienti per la conservazione delle correnti covarianti per traslazione e delle correnti conformi. Si possono interpretare questi teoremi come generalizzationi del teorema di Coleman.
Резюме
Предполагая, что энергетически-импульсный спектр содержится в закрытом переднем световом конусе, мы доказываем необходимые и достаточные условия для сохранения трансляционно ковариантных и конформных токов. Эти теоремы могут быть интерпретированы как обобщения теоремы Колемана.

In eq. (4) one should deal with smeared operators but we used a formal notation for simplicity. The appropriate set {A} can be the set of local operators or quasi-local operators of degree ≥N, whereN≥2..
