The Dirichlet problem of nonhomogeneous AA-harmonic equations in unbounded open sets and some estimates

Abstract In this paper, we study the Dirichlet problem for nonhomogeneous A -harmonic equations with Sobolev boundary values in unbounded open sets of R n . We prove the existence of solutions of nonhomogeneous A -harmonic equations with Sobolev boundary values in any unbounded open sets of R n . Then, we establish some estimates for their solutions.
