  • Let $\Cal{L}=\text{div}A\nabla$ be a real, symmetric second order elliptic operator with bounded measurable coefficients. Consider the elliptic equation $\Cal{L}u=0$ in a bounded Lipschitz domain $\Omega$ of $\Bbb{R}^n$. We study the relationship between the solvability of the $L^p$ Dirichlet problem $(D)_p$ with boundary data in $L^p(\partial \Omega)$ and that of the $L^q$ regularity problem $(R)_q$ with boundary data in $W^{1,q}(\partial \Omega)$, where $1
