A Unified Formula of a Series of Breather Solitons for the Nonlinear Schrödinger Equation.

In this paper, a unified formula of a series of breather soliton solutions for the standard (1+1) dimension nonlinear Schrödinger equation is obtained through Exp-function method. Further, by using appropriate transformation, based on solutions obtained, breather soliton solutions of the variable coefficient nonlinear Schrödinger equation are also obtained. One free function of time t and several arbitrary parameters are involved to generate abundant wave structures. [ABSTRACT FROM AUTHOR]
