Summation formula inequalities for eigenvalues of Schrödinger operators
arXiv:1605.01925
Abstract
We derive inequalities for sums of eigenvalues of Schrödinger operators on finite intervals and tori. In the first of these cases, the inequalities converge to the classical trace formulae in the limit as the number of eigenvalues considered approaches infinity.
