Singular spectral shift function for Schrödinger operators

Nurulla Azamov, Tom Daniels

Let $H_{0} = - Δ + V_{0} (x)$ be a Schroedinger operator on $L_{2} (R^{ν}),$ $ν = 1, 2,$ or 3, where $V_{0} (x)$ is a bounded measurable real-valued function on $R^{ν} .$ Let $V$ be a…

Spectral flow and resonance index

Nurulla Azamov

It has been shown recently that spectral flow admits a natural integer-valued extension to essential spectrum. This extension admits four different interpretations; two of them are…

A remark on imaginary part of resonance points

Nurulla Azamov, Tom Daniels

In this paper we prove for rank one perturbations that negative two times reciprocal of the imaginary part of resonance point is equal to the rate of change of the scattering phase…
