Abstract
We consider a differential expression \({H=\nabla^*\nabla+V}\), where \({\nabla}\) is a Hermitian connection on a Hermitian vector bundle E over a manifold of bounded geometry (M, g) with metric g, and V is a locally integrable section of the bundle of endomorphisms of E. We give a sufficient condition for H to have an m-accretive realization in the space L p(E), where 1 < p < +∞. We study the same problem for the operator Δ M + V in L p(M), where 1 < p < ∞, Δ M is the scalar Laplacian on a complete Riemannian manifold M, and V is a locally integrable function on M.
