| Abstract: | Nonlinear excitation in self gravitating quantum dusty plasma is analysed from the viewpoint of perturbation theory. A plasma configuration consisting of electron, ion and dust particles are treated by reductive perturbation theory, to deduce two coupled modified KdV equations. The soliton like solutions of such coupled systems are obtained with the help of another multiple scale perturbation theory. This leads to the variation of soliton amplitude and velocity due to the several interaction terms. |
