利用投射方程法和变量分离法,得到了(2+1)维非对称Nizhnik-Novikov-Veselov系统的新显式精确解.根据得到的孤波解,构造出了该系统的多孤子和分形孤子.
By the projective equation approach and the variable separation method,a series of excitations of the (2 + 1 )dimensional asymmetric Nizhnik-Novikov-Veselov system is derived.Based on the derived solitary wave excitation,we obtain multi solitons and fractal solitons of the system.
