On Perturbations of Quasiperiodic Schrödinger Operators
Helge Krüger
Using relative oscillation theory and the reducibility result of Eliasson,
we study perturbations of quasiperiodic Schrödinger operators. In particular,
we derive relative oscillation criteria and eigenvalue asymptotics for
critical potentials.
