摘要
运用Maple计算软件,研究(3+1)维广义浅水波方程,给出该方程的lump解并画图加以说明;运用交换公式,研究(2+1)维破碎孤子方程,推出其Bcklund变换,并利用求得的Bcklund变换得到方程的多孤子解.
By means of symbolic computation with Maple,a class of lump solutions to the(3+1)-dimensional generalized shallow water equation is studied,and the Bcklund transformation(BT)for a(2+1)-dimensional breaking soliton euqation has been generated in bilinear form.Based on the BT,the multi-soliton solutions can be derived by apurely algebraic procedure.
