By using a gauge transformation between thetwo eigenvalue problems, we obtain a correspondence between the hie -rarchy of nonlinear evolution equations associated with the Kaup-Newelleigenvalue problem and the hie rarchy of nonlinear evolution equationsassociated with the AKNS eigenvalue problem.

利用规范变换,我们得到了与Kaup-Newell特征值问题相联系的一族非线性演化方程和与AKNS特征值问题相联系的一族非线性演化方程之间的一个对应关系,并给出了Kaup-Newell系统的Darboux变换及其证明。

Further, with the help of Riccati equations, an infinite number of conservation laws for the solton hierarchy are deduced. For the sake of simplicity, taking the general TD hierarchy as an illustrative example, we prove that its 2×2 Lenard pair of operators forms a Hamiltonian pair. Thus the isospectral evolution TD hierarchy is the general Hamiltonian system and possesses the Bi-Hamiltonian structures and Multi-Hamiltonian structures. By using the method of derivation of functional under some constraint condition, a complete one-to-one correspondence between the Hamiltonian functions of the hierarchy and its conservation density functions can be built. These results can also be applied to the isospectral evolution soliton hierarchy of this paper. Finally, there's a gauge transformation between the spectral problem of this paper and the AKNS system. Moreover, the potentials in these spectral problems satisfy the general Miura transformation, the corresponding relationship between the two soliton hierarchies is also given.

进一步本文还通过特征函数的组合关系所满足的Riccati方程,得到了该等谱方程族的无穷多个守恒律;为简便起见,本文以广义TD族为例,由它的2×2 Lenard算子对的性质证明了此算子对为Hamilton算子对,这说明广义TD族是广义Hamilton系统且具有Bi-Hamilton结构和Multi-Hamilton结构;进而利用它的依赖于谱参数的一般守恒密度的积分在约束条件下求泛函导数的方法,得到了广义TD族的Hamilton函数与守恒密度之间的对应关系,这些性质对于由本文提出的2×2谱问题所导出的等谱孤子族仍成立;另外此谱问题与AKNS系统存在着规范变换,位势之间有广义Miura变换,而孤子方程之间也满足一定的等价关系。
