| Popis: | For a weakly nonuniform medium, a solitary wave solution of the variable‐coefficient nonlinear Schrodinger equation is obtained through second order in the expansion parameter. From a generalization of the second‐order result, the form of the solution to all orders is derived from which the conditions for an exact, distortionless solitary wave in a nonuniform medium are obtained. By use of a transformation, these results are shown to apply a weakly dissipative medium. |
