Abstract: | Consider the operator
in
where q is a real function with q′ and
bounded. The spectrum of T is purely discrete and consists of simple eigenvalues. We determine their asymptotics
and we extend these results for complex q.Communicated by Bernard Helffersubmitted 23/04/04, accepted 26/10/04 |
