Absence of eigenvalues of non-selfadjoint Schrödinger operators on the boundary of their numerical range
Marcel Hansmann
We use a classical result of Hildebrandt to establish simple conditions for the absence of eigenvalues of non-selfadjoint discrete and continuous Schrödinger operators on the bound…

From spectral theory to bounds on zeros of holomorphic functions
Marcel Hansmann, Guy Katriel
We show how eigenvalue estimates for linear operators can be used to obtain new Blaschke type bounds on zeros of holomorphic functions on the unit disk.
