By choosing the special values of parameters in the hierarchy, the hierarchies of the general TD, TD, the general C-KdV and C-KdV can be obtained. In order to investigate the Hamiltonian structure of this soliton hierarchy, a new Lenard gradient sequence {Gj} and its corresponding 2×2 Lenard pair of operators are introduced.

You decide to leave that hierarchy in place because you believe that, although the Circle and Ellipse are related, you don't want to have nonabstract leaf classes in your hierarchy, and several implementation problems occur when you try to derive the Circle class from the Ellipse class.

因为你相信，虽然 Circle 和 Ellipse 是有关系的，但是在你的类继层次内，你不想要非抽象的叶子类，所以你决定使用这个层次。当你尝试从 Ellipse 类派生 Circle 类的时候，会发生一些实现上的问题。

The purpose of this paper is to give the way of solving the noncommutative KP hierarchy and noncommutative constraint KP hierarchy and their bi-Hamiltonian structures.

本文试图解决一般情形下的非交换KP系列及其对应约束下的cKP系列的求解问题和它们的双Hamiltonian结构。
