Local Lipschitz regularity of vector valued local minimizers of variational integrals with densities depending on the modulus of the gradient

If u : R(n) superset of Omega -> R(M) locally minimizes the functional integral(Omega) h(vertical bar del u vertical bar) dx with h such that h'(t)/t <= h '' (t) <= c (1 + t(2))(omega) h'(t)/t for all t >= 0, then u is locally Lipschitz independent of the value of omega >= 0.
