A Criterion for Hill Operators to be Spectral Operators of Scalar Type
Fritz Gesztesy, Vadim Tkachenko
We derive necessary and sufficient conditions for a Hill operator (i.e., a one-dimensional periodic Schrödinger operator) to be a spectral operator of scalar type.…

Spectral Properties of a Class of Reflectionless Schrödinger Operators
Fritz Gesztesy, Peter Yuditskii
We prove that one-dimensional reflectionless Schrödinger operators with spectrum a homogeneous set in the sense of Carleson, belonging to the class introduced by Sodin and Yuditski…
