Eigenvalues of Schrödinger Operators with Potential Asymptotically Homogeneous of Degree − 2


We strengthen and generalise a result of Kirsch and Simon on the behaviour of the function NL(E), the number of bound states of the operator L = ∆ + V in Rd below −E. Here V is a bounded potential behaving asymptotically like P (ω)r−2 where P is a function on the sphere. It is well known that the eigenvalues of such an operator are all nonpositive, and… (More)
