DISCRETE SCHRODINGER OPERATORS WITH DECAYING AND OSCILLATING POTENTIALS
Journal article, 2024
The paper is devoted to a family of discrete one-dimensional Schodingeroperators with power-like decaying potentials with rapid oscillations. In particular, the potential V(n)=lambda n(-alpha)cos(pi omega n beta)with1<beta<2 alpha, it is proved that the spectrum is purely absolutely continuous on the spectrum of the Laplacian
