Boundary value problems in graph Lipschitz domains in the plane with A∞-measures on the boundary

We prove several results for the Dirichlet, Neumann and Regularity problems for the Laplace equation in graph Lipschitz domains in the plane, considering A∞-measures on the boundary. More specifically, we study the Lp,1-solvability for the Dirichlet problem, complementing results of [25] and [10]. T...

Sumario:We prove several results for the Dirichlet, Neumann and Regularity problems for the Laplace equation in graph Lipschitz domains in the plane, considering A∞-measures on the boundary. More specifically, we study the Lp,1-solvability for the Dirichlet problem, complementing results of [25] and [10]. Then, we study Lp-solvability of the Neumann problem, obtaining a range of solvability which is empty in some cases, a clear difference with the arc-length case. When it is not empty, it is an interval, and we consider solvability at its endpoints, establishing conditions for Lorentz space solvability when p>1and atomic Hardy space solvability when p =1. Solving the Lorentz endpoint leads us to a two-weight Sawyer-type inequality, for which we give a sufficient condition. Finally, we show how to adapt to the Regularity problem the results for the Neumann problem.
