Abstract

The complex Toda chain (CTC) is known to describe the N-soliton train interactions in adiabatic approximation for several nonlinear evolution equations: the nonlinear Schrödinger equation (NLS), the modified NLS, higher NLS. We briefly review and extend the results in order to treat several types of perturbations of the above-mentioned equations. In particular we consider analytically the effects of quadratic and periodic external potentials as perturbations. We also briefly analyze the Hamiltonian properties of the CTC.
