摘要
In this paper, a generalized variable-coefficient nonlinear Schrodinger equation with higher-order and gain/loss effects which can be used to describe the femtosecond pulse propagation is analytically investigated via symbolic computation. Under sets of coefficient constraints, such an equation is transformed into a completely integrable constant-coefficient higher-order nonlinear Schrodinger equation. Furthermore, through the transformation, the dark one-and two-soliton solutions for the generalized variable-coefficient he higher-order nonlinear Schrodinger equation are derived by means of the bilinear method.
