一类变系数非线性Schrǒdinger方程的对称群分类和容许变换(英文)

Symmetry classes and allowed transformations of a class of variable coefficient nonlinear schrdinger equations

从对称群和容许变换的角度讨论一类变系数非线性Ｓｃｈｒｏｄｉｎｇｅｒ方程。

In this paper, We discuss a class of variable coefficient nonlinear Schrdinger equations from the point of view of its symmetries and allowed transformations. All equations considered having nontrival Lie point symmetry group G are identified.
