Given an open and bounded set ω n and a family - = (X 1, ..., X m) of Lipschitz vector fields on ω, with m ≤ n, we characterize three classes of local functionals defined on first-order X-Sobolev spaces, which admit an integral representation in terms of X, i.e. F (u, A) = A f (x, u (x), X u (x)) x, with f being a Carathéodory integrand.

Abstract
Given an open and bounded set ω n and a family - = (X 1, ..., X m) of Lipschitz vector fields on ω, with m ≤ n, we characterize three classes of local functionals defined on first-order X-Sobolev spaces, which admit an integral representation in terms of X, i.e. F (u, A) = A f (x, u (x), X u (x)) x, with f being a Carathéodory integrand.File in questo prodotto:
