Annotation
We study some peculiarities of the small dispersion limit for the Gardner equation with positive and negative sign of cubic nonlinear term and positive quadratic nonlinear term by numerical modeling of evolution of long bell–shaped pulse with a polarity, opposite to the sign of the quadratic nonlinearity. A statistical and spectral analysis of wave fields is carried out.
