Description
The reductive perturbation technique is applied to obtain the dust acoustic wave equation from the governing equations for dust grains in plasma. Some electrons and ions can be trapped in the charged dust potential and the populations of these two particles will be described by the Maxewellian distribution. The growth rate can be determined by applying a long-wavelength perturbation to the perpendicular direction of the dust acoustic soliton.
