该族中第二个方程就是修正Sawada-Kotera方程的推广形式
) 摘要: 从修正Sawada-Kotera方程出发,引入一个具有两个位势的3×3的矩阵谱问题
可积非线性演化方程
从而给出了修正Sawada-Kotera方程的Lax对
并由此得到一族新的非线性演化方程
) Abstract: Based onthe modified Sawada-Kotera equation, we introduce a 3×3 matrix spectral problem with two potentials and derive a hierarchyof new nonlinear evolution equations
The second member in thehierarchy is a generalization of the modified Sawada-Koteraequation, by which a Lax pair of the modified Sawada-Kotera equationis obtained
Moreover, infinite sequences of conserved quantities ofthe first two nonlinear evolution equations in the hierarchy and themodified Sawada-Kotera equation are constructed with the aid oftheir Lax pairs
