Trace Formulas and a Borg-type Theorem for CMV Operators with Matrix-valued Coefficients
Maxim Zinchenko
We prove a general Borg-type inverse spectral result for a reflectionless unitary CMV operator (CMV for Cantero, Moral, and Velázquez) associated with matrix-valued Verblunsky coef…
Essential Closures and AC Spectra for Reflectionless CMV, Jacobi, and Schrödinger Operators Revisited
Fritz Gesztesy, Konstantin A. Makarov, Maxim Zinchenko
We provide a concise, yet fairly complete discussion of the concept of essential closures of subsets of the real axis and their intimate connection with the topological support of…
Borg-Marchenko-type Uniqueness Results for CMV Operators
Stephen Clark, Fritz Gesztesy, Maxim Zinchenko
We prove local and global versions of Borg-Marchenko-type uniqueness theorems for half-lattice and full-lattice CMV operators (CMV for Cantero, Moral, and Velazquez \cite{CMV03}).…
Local Spectral Properties of Reflectionless Jacobi, CMV, and Schrödinger Operators
Fritz Gesztesy, Maxim Zinchenko
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…
Variations on a Theme of Jost and Pais
Fritz Gesztesy, Marius Mitrea, Maxim Zinchenko
We explore the extent to which a variant of a celebrated formula due to Jost and Pais, which reduces the Fredholm perturbation determinant associated with the Schrödinger operator…
