On the discrete spectrum of non-selfadjoint operators
Michael Demuth, Marcel Hansmann, Guy Katriel
We prove quantitative bounds on the eigenvalues of non-selfadjoint unbounded operators obtained from selfadjoint operators by a perturbation that is relatively-Schatten. These boun…

Inequalities for the eigenvalues of non-selfadjoint Jacobi operators
Marcel Hansmann, Guy Katriel
We prove Lieb-Thirring-type bounds on eigenvalues of non-selfadjoint Jacobi operators, which are nearly as strong as those proven previously for the case of selfadjoint operators b…
