On Perturbations of Quasiperiodic Schroedinger Operators
Helge Krueger
Using relative oscillation theory and the reducibility result of Eliasson, we study perturbations of quasiperiodic Schroedinger operators. In particular, we derive relative oscilla…

Effective Pruefer Angles and Relative Oscillation Criteria
Helge Krueger, Gerald Teschl
We present a streamlined approach to relative oscillation criteria based on effective Pruefer angles adapted to the use at the edges of the essential spectrum. Based on this we pro…
