在符号计算软件Maple的帮助下,利用投射方程法和变量分离法,得到了(3+1)维Jimbo-Miwa(JM)方程的新显式精确解.根据得到的孤立波解,研究了JM方程新颖的局域激发.
With the help of the symbolic computation system Maple and a projective equation and a linear variable separation method,new exact solutions of the (3+1)-dimensional Jimbo-Miwa equation are derived.Based on the derived solitary wave solution,some novel localized excitations are investigated.
