Lipschitz estimates for systems with ellipticity conditions at infinity

In the general vector-valued case N ≥ 1, we prove the Lipschitz continuity of local minimizers to some integrals of the calculus of variations with p, q-growth conditions only for |Du| → +∞ and without further structure conditions on the integrand. Moreover, the regularity results are applied to weak solutions to nonlinear elliptic systems in divergence form.
