Some remarks on the regularity of minimizers of integrals with anisotropic growth

Comment.Math.Univ.Carolinae 34,4 (1993) 597-611.

Abstract:We prove higher integrability for minimizers of some integrals of the calculus of variations; such an improved integrability allows us to get existence of weak second derivatives.

Keywords: regularity, minimizers, integral functionals, anisotropic growth
