摘要
构造了一个带有任意光滑函数的等谱问题,利用屠规彰格式得到广义KN 方程族及其Hamilton结构,并且当f=0时,变为著名的KN谱,当f=-12qr时,变为Qiao谱.
Constructing an isospectral problem with an arbitrary smooth function, we propose a type of generalized KN hierarchy and its bi-Hamiltonian structure by the use of Tu Guizhang’s model. Especially, when f=0, the isospectral problem is described as the well-known KN hierarchy, furthermore, when f=-12qr, the isospectral problem is written as the Qiao’s spectral.
