借助Riccati方程展开法和线性变量分离法,得到了(2+1)维非对称Nizhnik-NovikovVeselov系统(ANNV)的复合波解.根据得到的孤立波解,研究该系统的复合波局域激发和分形孤子结构.
By the Riccati equation expansion method and a variable separation method,a series of complex wave solutions of the (2+1)-dimensional asymmetric Nizhnik-Novikov-Veselov system are derived. Based on the derived solitary wave solutions, some nove complex wave localized excitations and the fractal soliton structures of the system are studied.
