WebAbstract. 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. WebTheorem 3 (Noether’s Theorem{Simpli ed). Suppose the Lagrangian has a time-independent di erentiable symmetry, that is a smooth one-parameter variation x(s) under which it is invariant. Then the quantity C= (@ x_iL)@ sxi is conserved in time. Proof. Given a smooth variational symmetry of the Lagrangian x(s) where x(0) = x, we know that @
