Trace Formulas for Jacobi Operators in Connection with Scattering Theory for Quasi-Periodic Background

Johanna Michor and Gerald Teschl

Abstract
We investigate trace formulas for Jacobi operators which are trace class perturbations of quasi-periodic finite-gap operators using Krein's spectral shift theory. In particular we establish the conserved quantities for the solutions of the Toda hierarchy in this class.
