一族新的非线性发展方程系统及其Hamilton结构

A Hierarchy of New Nonlinear Evolution Systems and Its Hamiltonian Structure

考虑一种新的等谱问题，由此导出一族新的非线性发展方程系统，并利用迹的恒等式建立起这族新系统的双Ｈａｍｉｌｔｏｎ结构．

A new isospectral problem is considered,from which a hierarchy of new nonlinear evolution systems is derived.By using the trace identity,we construct the Hamiltonian structure of this hierarchy.
