Abstract
We consider very weak minimisers u of variational integrals integral F (x, Du(x)) dx and very weak solutions u of nonlinear elliptic systems div A(x, u, Du) = 0; we prove higher integrability for the gradient Du without any homogeneity on xi --> A(x, u, xi), thus improving on a re sult by Iwaniec and Sbordone.
