Second Order Regularity for the A-Laplace Operator. Mediterr. J. Math. 7, 283–296 (2010). The published version includes some minor revisions after peer review and is available online at: https://doi.org/10.1007/s00009-010-0053-0In this paper we establish second order regularity for the quasilinear elliptic equation ΔAu = f, where ΔA is the so called A-Laplace operator.enApplied MathematicsPure MathematicsMathematical SciencesA-LaplacianOrlicz Sobolev spaceSecond derivativeArticle
