广义五阶非线性薛定谔方程的怪波与呼吸子的复合波解
Hybrid Rogue Wave and Breather Solutions for the Generalized Fifth-order Nonlinear Schrödinger Equation
基于规范变换,为广义五阶非线性薛定谔方程建立达布变换。应用达布变换的可迭代性质,获得该方程的重达布变换。把广义五阶非线性薛定谔方程Lax对的两组特解代入二重和三重达布变换中,获得该方程的怪波与呼吸子的复合波解。研究表明怪波和呼吸子可以在复合波解中独立存在。
Hybrid rogue wave and breather solutions for the generalized fifth-order nonlinear Schrödinger equation are investigated by extended Darboux transformation. Firstly, the Darboux transformation is constructed based on gauge transformation for the equation; and then, the N-fold Darboux transformation is derived by utilizing the iterative property of the Darboux transformation; finally, the hybrid rogue wave and breather solutions of the equation are obtained through substituting two sets of the particular solution for the Lax pair of the equation into two-fold and three-fold Darboux transformation. The results indicate that different parameters have different effects on hybrid solutions. As a novel result, rogue waves and breathers are able to exist independently on.
