On the singularities of the spectral shift function for some tight-binding models

Marouane Assal, Olivier Bourget, Diomba Sambou +1

We consider perturbed discrete tight-binding models in ${\ell }^2({\mathbb{Z}}_h,\mathcal{G})$ describing union of quantum particles with localized interactions, where ${\mathbb{Z}}_h$ is…
