摘要/Abstract

摘要：

该文借助于零曲率方程得到了一个与3×3矩阵谱问题相关的形变Boussinesq型非线性演化可积方程族.通过考虑两个线性谱问题，给出了方程族中前两个方程的无穷多守恒律.借助于Darboux变换得到了第一个形变Boussinesq型方程的一些显式解.

关键词: 形变Boussinesq型方程族, 守恒律, Darboux变换

Abstract:

In this paper, we propose a deformed Boussinesq-type integrable hierarchy of nonlinear evolution equations associated with a 3×3 matrix spectral problem by using the zero-curvature equation. Based on two linear spectral problems, we obtain the infinite many conservation laws of the first two members in the hierarchy. Some explicit solutions to the first deformed Boussinesq-type equation are given by utilizing the Darboux transformation.

Key words: Deformed Boussinesq-type hierarchy, Conservation laws, Darboux transformation
