Rogue wave solutions of the nonlinear Schrödinger eqution with variable coefficients
Changfu Liu Yan Yan Li Meiping Gao Zeping Wang Zhengde Dai Chuanjian Wang
In this paper, a unified formula of a series of rogue wave solutions for the standard (1+1)-dimensional nonlinear Schrödinger equation is obtained through exp-function method. Further, by means of an appropriate transformation and previously obtained solutions, rogue wave solutions of the variable coefficient Schrödinger equation are also obtained. Two free functions of time 𝑡 and several arbitrary parameters are involved to generate a large number of wave structures.
