摘要
运用秩的概念将微分方程式在行波变换下的Jacobi椭圆函数展开法进行推广,应用到非线性发展方程组的求解中.通过直接找出方程组的精确解来证实这类微分方程组周期解的存在性问题.研究表明,当模数m→1时周期解退化为钟型及扭结型孤立波解.
A coupled KdV system was solved by using the generalized Jacobian elliptic function expansion method. As a consequence, abundant families of periodic solutions expressed with Jacobian elliptic function are obtained to expose the existence of periodic solutions for the considered system. When the modulus m tends to 1, those periodic solutions degenerate to the corresponding solitary wave solution, including bell-type and kink-type excitations.
