Abstract: This paper continues the study of the mixed problem for the Laplacian. We consider a bounded Lipschitz domain $ \Omega \subset \mathbf {R}^n$, $ n\geq 2$, with boundary that is decomposed as $ \partial \Omega =D\cup N$, with $ D$ and $ N$ disjoint. We let $ \Lambda $ denote the boundary of $ D$ (relative to $ \partial \Omega $) and impose conditions on the dimension and shape of $ \Lambda $ and the sets $ N$ and $ D$. Under these geometric criteria, we show that there exists $ p_0>1$ depending on the domain $ \Omega $ such that for $ p$ in the interval $ (1,p_0)$, the mixed problem with Neumann data in the space $ L^p(N)$ and Dirichlet data in the Sobolev space $ W^{1, p}(D) $ has a unique solution with the non-tangential maximal function of the gradient of the solution in $ L^p(\partial \Omega )$. We also obtain results for $ p=1$ when the Dirichlet and Neumann data come from Hardy spaces, and a result when the boundary data comes from weighted Sobolev spaces.
