Computations of eigenvalues and resonances on perturbed hyperbolic surfaces with cusps
Michael Levitin, Alexander Strohmaier
In this paper we describe a simple method that allows for a fast direct computation of the scattering matrix for a surface with hyperbolic cusps from the Neumann-to-Dirichlet map o…

A two-parameter eigenvalue problem for a class of block-operator matrices
Michael Levitin, Hasen Mekki Öztürk
We consider a symmetric block operator spectral problem with two spectral parameters. Under some reasonable restrictions, we state localisation theorems for the pair-eigenvalues an…
