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

J. Michor and G. Teschl

Keywords: Scattering, Toda hierarchy, Trace formulas.

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.
