Boundary regularity for quasilinear elliptic equations with general Dirichlet boundary data

Analysis of PDEs 2018-11-12 v1

Abstract

We study global regularity for solutions of quasilinear elliptic equations of the form ÷\A(x,u,u)=÷\F\div \A(x,u,\nabla u) = \div \F in rough domains Ω\Omega in Rn\R^n with nonhomogeneous Dirichlet boundary condition. The vector field \A\A is assumed to be continuous in uu, and its growth in u\nabla u is like that of the pp-Laplace operator. We establish global gradient estimates in weighted Morrey spaces for weak solutions uu to the equation under the Reifenberg flat condition for Ω\Omega, a small BMO condition in xx for \A\A, and an optimal condition for the Dirichlet boundary data.
