Boundary regularity for the polyharmonic Dirichlet problem

Analysis of PDEs 2025-02-25 v2

Abstract

In this paper we prove that any solution of the mm-polyharmonic Poisson equation in a Reifenberg-flat domain with homogeneous Dirichlet boundary condition, is Cm1,α\mathscr{C}^{m-1,\alpha} regular up to the boundary. To achieve this result we extend the Nirenberg method of translations to operators of arbitrary order, and then use some Mosco-convergence tools developped in a previous paper.
