利用Gelfand-Dickey算子的分解导出了GKdV方程的n个B?cklund-Darboux(BD)变换及对应的对称的精确形式.这一结果推广了Lou等最近关于KdV,Kadomtsev-Petviashvilli(KP)等方程的BD变换同非局所对称性的结果.作为副产品同时给出Generalized-KdV方程的行列式形式解.Explicit expressions of n B?cklund-Darboux (BD) transformations and corresponding symmetries for generalized KdV (GKdV) equation, were constructed by using factorization of Gelfand-Dickey operator. This extends Lou's recent result about the BD transformations and non-local symmetries for KdV, Kadomtsev-Petviashvilli equations. As a by-product, we also derive a representation of Wronskian determinant for the GKdV solution.
