Abstract :
Let λ : U(1) → GL (V) be a linear representation. Lagrangians defined on J1(T*M × V)whose universal current form is gauge invariant, are described in terms of gauge invariant Lagrangians and invariant functions on V. A characterization of gauge invariant Lagrangians depending on matter fields only, that is, L : J1V → ℝ, is also obtained.
