Query: Strictly elliptic operators with Dirichlet boundary conditions on spaces
  of continuous functions on manifolds   We study strictly elliptic differential operators with Dirichlet boundary
conditions on the space $\mathrm{C}(\overline{M})$ of continuous functions on a
compact, Riemannian manifold $\overline{M}$ with boundary and prove
sectoriality with optimal angle $\frac{\pi}{2}$.
