Spectral inequalities for Schroedinger operators with surface potentials
arXiv:0711.3473
Abstract
We prove sharp Lieb-Thirring inequalities for Schroedinger operators with potentials supported on a hyperplane and we show how these estimates are related to Lieb-Thirring inequalities for relativistic Schroedinger operators.
