Abstract
We prove the local Lipschitz continuity and the higher differentiability of local minimizers of functionals of the form (Formula Presented) with non-autonomous integrand F (x, ζ) which is degenerate convex with respect to the gradient variable. The main novelty here is that the results are obtained assuming that the partial map x → D ζ F (x, ζ) has weak derivative in the almost critical Zygmund class L n log α L and the datum f is assumed to belong to the same Zygmund class.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
