MODIFIED KORTEWEG-de VRIES SOLITONS ON DUST ION ACOUSTIC SOLITARY WAVES IN A WARM PLASMA WITH ELECTRONS’ DRIFT MOTION
In this investigation, only compressive solitons are seen to exist in a dusty plasma consisting of positive ions, electrons and immobile negatively charged dust grains in presence of electrons’ drift velocity The compressive mKdV solitons of small amplitude exist in a small region The amplitude becomes higher for smaller values of (= ion to electron temperature ratio).
mKdV equation, dust ion acoustic wave, drifting effect, ion temperature, soliton, dusty plasma, electron inertia.
