(2+1)维孤子系统的多孤子解和分形结构

Multi-soliton solutions and fractal structures in a (2 + 1)-dimensional soliton system

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.
