WEIGHTED A PRIORI ESTIMATES FOR SOLUTION OF （-△）mu = f WITH HOMOGENEOUS DIRICHLET CONDITIONS

摘要

Let u be a weak solution of (-△)mu = f with Dirichlet boundary conditions in a smooth bounded domain Ω  Rn. Then, the main goal of this paper is to prove the following a priori estimate:‖u‖ Wω2 m,p(Ω) ≤ C ‖f‖ Lωp (Ω),where ω is a weight in the Muckenhoupt class Ap.
