摘要
利用广义映射法,研究非线性薛定谔系统,得到了它的周期波解、具有周期性行为的孤波解和雅科比椭圆函数解,并解释了两列互相垂直的具有周期性行为的孤波相互作用后产生新的孤波结构的现象。
With the help of a general mapping approach, abundant exact exctiations of a nonlinear Schroedinger system are obtained, which include preodic wave solutions, Jacobian double preodic wave solutions and some new solitary excitations with preodic behaviors. Meanwhile we discuss a new solitary structure derived from two solitary waves with periodic behaviors travelling in two perpendicular directions.
