Multisoliton solutions and integrability aspects of coupled nonlinear Schrodinger equations
Using Painleve singularity structure analysis, we show that coupled
higher-order nonlinear Schrodinger (CHNLS) equations admit Painleve property.
Using the results of Painleve analysis, we succeed in Hirota bilinearizing the
CHNLS equations, one soliton and two soliton solutions are explictly obtained.
Lax pairs are explictly constructed.Comment: Eight pages and six figures. Physical Review E (to be appear
