Abstract: | A modified Zakharov-Kuznetsov equation for small but finite amplitude dust acoustic waves in a magnetized votex-like ion distribution dusty plasma is obtained in this paper. It
seems that there are instability for a soliton under higher-order
transverse perturbations in this system. There is a certain
critical value 4λ0. If the ratio of the wave length of
the higher-order perturbations to the width of the soliton is
larger than this critical value, the solitary wave is unstable,
otherwise it is stable. |
