Local Spectral Properties of Reflectionless Jacobi, CMV, and Schrödinger Operators
arXiv:0803.3177
Abstract
We prove that Jacobi, CMV, and Schrödinger operators, which are reflectionless on a homogeneous set E (in the sense of Carleson), under the assumption of a Blaschke-type condition on their discrete spectra accumulating at E, have purely absolutely continuous spectrum on E.
