Recycling Givens rotations for the efficient approximation of pseudospectra of band-dominated operators
Marko Lindner, Torge Schmidt
We study spectra and pseudospectra of certain bounded linear operators on . The operators are generally non-normal, and their matrix representation has a chara…

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…
