A Dynamical System Approach To The Inverse Spectral Problem For Hankel Operators: The General Case
Zhehui Liang, Sergei Treil
We study the inverse problem for the Hankel operators in the general case. Following the work of Gérard--Grellier, the spectral data is obtained from the pair of Hankel operators $…

A Dynamical System Approach to the Inverse Spectral Problem for Hankel Operators: A Model Case
Zhehui Liang, Sergei Treil
We present an alternative proof of the result by P. Gerard and S. Grellier, stating that given two real sequences , satisfying the intertwi…
