Visibility of quantum graph spectrum from the vertices

Christian Kühn, Jonathan Rohleder

We investigate the relation between the eigenvalues of the Laplacian with Kirchhoff vertex conditions on a finite metric graph and a corresponding Titchmarsh-Weyl function (a param…

Spectral theory for Schrödinger operators with $δ$ -interactions supported on curves in $R^{3}$

Jussi Behrndt, Rupert L. Frank, Christian Kühn +2

The main objective of this paper is to systematically develop a spectral and scattering theory for selfadjoint Schrödinger operators with $δ$ -interactions supported on closed curve…

On eigenvalue asymptotics for strong delta-interactions supported by surfaces with boundaries

J. Dittrich, P. Exner, Ch. Kühn +1

Let $S \subset R^{3}$ be a $C^{4}$ -smooth relatively compact orientable surface with a sufficiently regular boundary. For $β \in R_{+}$ , let $E_{j} (β)$ denote the $j$ th negat…
