We consider a Schrödinger-type differential expression H V = * + V , where is a C -bounded Hermitian connection on a Hermitian vector bundle E of bounded geometry over a manifold of bounded geometry ( M , g ) with metric g and positive C -bounded measure d μ , and V is a locally integrable section of the bundle of endomorphisms of E . We give a sufficient condition for m -sectoriality of a realization of H V in L 2 ( E ) . In the proof we use generalized Kato’s inequality as well as a result on the positivity of u L 2 ( M ) satisfying the equation ( Δ M + b ) u = ν , where Δ M is the scalar Laplacian on M , b > 0 is a constant and ν 0 is a positive distribution on M .

AB - We consider a Schrödinger-type differential expression $H_V=\nabla ^*\nabla +V$, where $\nabla $ is a $C^{\infty }$-bounded Hermitian connection on a Hermitian vector bundle $E$ of bounded geometry over a manifold of bounded geometry $(M,g)$ with metric $g$ and positive $C^{\infty }$-bounded measure $d\mu $, and $V$ is a locally integrable section of the bundle of endomorphisms of $E$. We give a sufficient condition for $m$-sectoriality of a realization of $H_V$ in $L^2(E)$.
