Spectral approximation of aperiodic Schrödinger operators
Siegfried Beckus
We study the (Hölder-)continuous behavior of the spectra belonging to a family of linear bounded operators indexed by a topological space . For the cases of sel…

On the spectrum of operator families on discrete groups over minimal dynamical systems
Siegfried Beckus, Daniel Lenz, Marko Lindner +1
It is well known that, given an equivariant and continuous (in a suitable sense) family of selfadjoint operators in a Hilbert space over a minimal dynamical system, the spectrum of…
