在本文中,通过对一个新的广义AKNS谱问题的研究,得到AKNS方程族新的广义可积耦合方程族,其中等谱形式与非等谱形式分别得到讨论,给出相应的哈密顿系统.
In this letter, a general form of enlarged AKNS spectral problem is discussed, the corresponding hierarchies of AKNS integrable couplings are derived, including positive non-isospectral hierarchy and negative non-isospectral hierarchy. The Hamiltonian structure is presented also.
