Eigenvalue inequalities for Schrödinger operators on unbounded Lipschitz domains
Jussi Behrndt, Jonathan Rohleder, Simon Stadler
Given a Schrödinger differential expression on an exterior Lipschitz domain we prove strict inequalities between the eigenvalues of the corresponding selfadjoint operators subject…

Quasi boundary triples and semibounded self-adjoint extensions
Jussi Behrndt, Matthias Langer, Vladimir Lotoreichik +1
In this note semibounded self-adjoint extensions of symmetric operators are investigated with the help of the abstract notion of quasi boundary triples and their Weyl functions. Th…
