The surface to singular solitonic solution of the nonlinear Schrodinger equation

Abstract

One of the topical problems of mathematics is studying of nonlinear differential equations in partial derivatives. Investigation in this area is important, since the results get the theoretical and practical applications. There are some different approaches for solving of the equations. Methods of the theory of solitons allow to construct the solutions of the nonlinear differential equations in partial derivatives. One of the methods for solving of the equations is the inverse scattering method. The aim of the work is to construct a surface corresponding to a singular onesolitonic solution of the nonlinear Schrodinger equation with gravity in (1+1)-dimensions. In this work the construction of the surface in (1+1)-dimensions in Fokas-Gelfand sense is considered. According to the approach the nonlinear differential equations in (1+1)dimension are given in the form of zero curvature condition and are compatibility condition of the linear system equations. In this case there is a surface with immersion function. The surface defined by the immersion function is identified to the surface in three - dimensional space. Surface with coefficients of the first fundamental form corresponding to the singular onesolitonic solution of the nonlinear Schrodinger equation is found by soliton immersion.
