Gray soliton solution in the extended nonlinear Schrodinger equation
arXiv:nlin/0503048
Abstract
In the framework of extended nonlinear Schrodinger equation (ENSE) the classification of self-similar solutions by the relation between the amplitude and phase is performed. New solutions of ENSE - ``gray soliton'' and ``gray soliton chain'' are presented. The properties of these solutions and the possibility for using theirs in physical applications are discussed.
