Integrable Couplings of Soliton Equations by Perturbations I. A General Theory and Application to the KdV Hierarchy
Wen-Xiu Ma
A theory for constructing integrable couplings of soliton equations is developed by using various perturbations around solutions of perturbed soliton equations being analytic with…

Non-symmetry constraints of the AKNS system yielding integrable Hamiltonian systems
Wen-Xiu Ma, Si-Ming Zhu
This paper aims to show that there exist non-symmetry constraints which yield integrable Hamiltonian systems through nonlinearization of spectral problems of soliton systems, like…
