On an H^r(curl,O) estimate for a Maxwell-type system in convex domains

In bounded convex domains, the regularity estimates of a vector field $\u$ with its $\dv\u$, $\curl\u$ in $L^r$ space and the tangential components or the normal component of $\u$ over the boundary in $L^r$ space, are established for $1<r<\infty$. As an application, we derive an $H^r(\curl,\O)$ estimate for solutions to a Maxwell-type system with an inhomogeneous boundary condition in convex domains.
