Operator estimates for homogenization of the Robin Laplacian in a perforated domain

Andrii Khrabustovskyi, Michael Plum

Let $ε > 0$ be a small parameter. We consider the domain $Ω_{ε} := Ω ∖ D_{ε}$ , where $Ω$ is an open domain in $R^{n}$ , and $D_{ε}$ is a…

Singular Schrödinger operators with prescribed spectral properties

Jussi Behrndt, Andrii Khrabustovskyi

The paper deals with singular Schrödinger operators of the form \begin{gather*} -{\mathrm{d}^2\over \mathrm{d} x^2 } + \sum_{k\in\mathbb{Z} }γ_k δ(\cdot-z_k),\quad γ_k\in\mathbb{R}…
