摘要
利用屠规彰格式由一个与 AKNS形似的谱问题出发构造了等谱 (λ t=0)和非等谱 (λ t=λ n)孤子族.用迹恒等式 [1]建立了它的 Hamilton形式.随后对文 [2, 3]的一个结果作了改进,使之适应于特征算子中含谱参数的非等谱 Lax表示.进而给出这个孤子族的等谱和非等谱的 Lax表示.
A soliton hierarchy of isospectral (λ t=0) and non-isospectral (λ t=λ n) associated with a spectral resembing AKNS spectral problem is constructed by using the Tu Guizhang form.Its Hamilton formulation is established by using the trace identity.By generalizing the results given in reference [2, 3], the author makes it fit the Lax representation of non-isospectral with spectral parameter in characteristic operator, and gives the Lax represontation of soliton hierarchy with isospectral and non-isospectral.
