Limits of spectral measures for linearly bounded and for Poisson distributed random potentials
David Hasler, Jannis Koberstein
We show the existence of infinite volume limits of resolvents and spectral measures for a class of Schroedinger operators with linearly bounded potentials. We then apply this resul…

A note on the surjectivity of operators on vector bundles over discrete spaces
Jannis Koberstein, Marcel Schmidt
In this note we give a short and self-contained proof for a criterion of Eidelheit on the solvability of linear equations in infinitely many variables. We use this criterion to stu…
