Summary: We define the superpotentials for gauge-natural Parametrized Variational Problems (PVPs). In view of a definition of augmented PVPs, we show that a pure divergence Lagrangian has trivial equations also in the case of PVPs but, as it happens in the free case, it has a non-vanishing superpotential. We compute it.For the entire collection see [Zbl 1216.00039].
