在符号计算软件Maple的帮助下,利用改进的Riccati方程映射法得到了(2+1)维Zakharov-Kuznetsov方程(ZK)的新显式精确解.根据得到的解,研究了ZK方程的特殊孤子结构.
With the help of the symbolic computation system Maple and an improved Riccati equation mapping approach,a series of exact solutions of the(2 + 1)-dimensional Zakharov-Kuznetsov equation(ZK) is derived.Based on the derived solution,we obtain some special soliton structures.
