摘要
基于双Bell多项式方法,将Jimbo-Miwa-Like方程化为双线性形式,运用Bell多项式的相关性质,构造出方程的双Bell多项式B?cklund变换、双线性B?cklund变换、Lax对、无穷守恒律和孤子解。运用试探函数法和符号计算软件Mathematica获得方程的复合型解,并选取适当的参数,绘制一部分精确解的图像来说明性质。
The Jimbo-Miwa-Like equation is transformed into bilinear form based on the Bell-polynomial method,and double Bell polynomial Bäcklund transformation,bilinear Bäcklund transformation,Lax pair,infinite conservation law and solitons of the equation are derived through symbolic computation by using the relevant properties of Bell-polynomial.Then,the complex solutions are obtained by applying the trail function method and symbolic calculation software Mathematica,and some of graphs for exact solutions are made to illustrate their properties through selecting the appropriate parameters.
