Lattice representation and dark solitons of the Fokas-Lenells equation (1103.4701v1)
Published 24 Mar 2011 in nlin.SI
Abstract: This work is devoted to an integrable generalization of the nonlinear Schr\"odinger equation proposed by Fokas and Lenells. I discuss the relationships between this equation and other integrable models. Using the reduction of the Fokas-Lenells equation to the already known ones I obtain the N-dark soliton solutions.
