On $$m$$-accretive Schrödinger-type operators with singular potentials on manifolds of bounded geometry. (English) Zbl 1057.58013
Schrödinger type operators on manifolds with complex potentials are considered. The main result is a sufficient criterion for the operators to be $$m$$-accretive. The proof follows previous work of T. Kato [Ann. Sc. Norm. Super. Pisa, Cl. Sci., IV. Ser. 5, 105–114 (1978; Zbl 0376.47021)].
