Multisoliton solutions and integrability aspects of coupled nonlinear Schrodinger equations

摘要

Using Painleve singularity structure analysis, we show that coupledhigher-order nonlinear Schrodinger (CHNLS) equations admit Painleve property.Using the results of Painleve analysis, we succeed in Hirota bilinearizing theCHNLS equations, one soliton and two soliton solutions are explictly obtained.Lax pairs are explictly constructed.
