Il teorema di Noether in teoria di campo classica associa una corrente conservata ad ogni simmetria continua. Ci sono spesso delle ambiguità nella definizione della corrente, legate alla possibilità di aggiungere quantità che la cui divergenza è identicamente nulla off-shell, o quantità che si annullano on-shell.
Noether's theorem or Noether's first theorem states that every differentiable symmetry of the action of a physical system with conservative forces has a corresponding conservation law. The theorem was proven by mathematician Emmy Noether in 1915 and published in 1918. The action of a physical system is the integral over time of a Lagrangian function, from which the system's behavior can be determined by the principle of least action. This theorem only applies to continuous and …
