Recovering quantum graph spectrum from vertex data

Jonathan Rohleder

We study the question to what extent spectral information of a Schrödinger operator on a finite, compact metric graph subject to standard or $δ$ -type matching conditions can be rec…

An eigenvalue inequality for Schrödinger operators with $δ$ and $δ^{'}$ -interactions supported on hypersurfaces

Vladimir Lotoreichik, Jonathan Rohleder

We consider self-adjoint Schrödinger operators in $L^{2} (R^{d})$ with a $δ$ -interaction of strength $α$ and a $δ^{'}$ -interaction of strength $β$ , respectively, supported on a h…

Spectral analysis of selfadjoint elliptic differential operators, Dirichlet-to-Neumann maps, and abstract Weyl functions

Jussi Behrndt, Jonathan Rohleder

The spectrum of a selfadjoint second order elliptic differential operator in $L^{2} (R^{n})$ is described in terms of the limiting behavior of Dirichlet-to-Neumann maps, which…
