Query: Sobolev and Lipschitz regularity for local minimizers of widely
  degenerate anisotropic functionals   We prove higher differentiability of bounded local minimizers to some widely
degenerate functionals, verifying superquadratic anisotropic growth conditions.
In the two dimensional case, we prove that local minimizers to a model
functional are locally Lipschitz continuous functions, without any restriction
on the anisotropy.
