Oblique Derivative Problems for the Laplacian in Lipschitz Domains
Jill C. Pipher · Revista Matemática Iberoamericana · 1987
The aim of this paper is to extend the results of Calderón [1] and Kenig-Pipher [12] on solutions to the oblique derivative problem to the case where the data is assumed to be BMO or Hölder continuous.
