摘要
从一个2×2谱问题出发,导出了一族(1+1)维孤子方程.利用谱问题对应的Riccati方程获得该等谱方程族的无穷多个守恒律,进而得到其守恒密度.
Based on a 2×2spectral problem,an 1+1dimensional soliton hierarchy is presented.Then,an infinite number of conservation laws for the isospectral soliton hierarchy are deduced with the help of Riccati equations.Further,the relative conservation density is got.
