Spectral estimates for resolvent differences of self-adjoint elliptic operators

Jussi Behrndt, Matthias Langer, Vladimir Lotoreichik

The notion of quasi boundary triples and their Weyl functions is an abstract concept to treat spectral and boundary value problems for elliptic partial differential equations. In t…

Singular continuous spectrum of half-line Schrödinger operators with point interactions on a sparse set

Vladimir Lotoreichik

We say that a discrete set $X =\{x_n\}_{n\in\dN_0}$ on the half-line is sparse if the distances between neighb…
