Band edge localization beyond regular Floquet eigenvalues

Albrecht Seelmann, Matthias Täufer

We prove that localization near band edges of multi-dimensional ergodic random Schrödinger operators with periodic background potential in $L^{2} (R^{d})$ is universal. By this…

Protecting points from operator pencils

Albrecht Seelmann, Matthias Täufer, Krešimir Veselić

We classify all sets of the form $⋃_{t \in R} spec (A + tB)$ where $A$ and $B$ are self-adjoint operators and $B$ is bounded, non-negative, and non-zero. We show…

The reflection principle in the control problem of the heat equation

Michela Egidi, Albrecht Seelmann

We consider the control problem for the generalized heat equation for a Schroedinger operator on a domain with a reflection symmetry with respect to a hyperplane. We show that if t…
