AUTOMODULATION OF ONE-DIMENSIONAL WAVES BASED ON NONLINEAR SCHREDINGGER EQUATION WITH NONLIANERITY CUBIC-QUINTIC TYPE
It is shown that nonlinear Schredinger equation with nonlinearity cubic-quintic type has a localized solution moving with constant velocity without dispersion. This solution is found by straight method and it contains the well-known solution of cubic nonlinear Schredinger equation.
