Abstract
Let P(ฯ, โ) be an elliptic operator with weight ฯ, and let u be a solution in some Lipschitz domains to โP(ฯ, โu)+Wโu+Vu=0 with sharp singular potentials W and V. The weighted doubling estimates, the weighted threeโball inequalities and the unique continuation at the boundary for solution u of the Neumann problem are established in this paper.
