REGIONS UDC 513 9It is proved that the discrete spectrum of the operator -~ + q(x) in the space L2(E2k) (k -> ~)t where q(x) is a measurable complex-valued function satisfying the condition ~(x) l ---Ce -~ |xl, having no finite limit points, and for k =1 the discrete spectrum consists of a finite number of points.Consider the minimal operator A n generated by the differential operator
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
