Abstract
In this paper, we have studied the dust acoustic (DA) solitons and dressed solitons under the influence of polarization force in a dusty plasma composed of negatively charged dust fluid, Maxwellian electrons and generalized (r, q) distributed ions. The expression of polarization force is modified due to the presence of generalized (r, q) distributed ions hence the effect of polarization force. By imposing the reductive perturbation method, the KdV equation and KdV type inhomogeneous equation are derived to study DA solitons and dressed solitons. The stationary solutions of these equations have been derived using the renormalization method. The stability analysis of solitons has also been carried out. The contribution of higher-order corrections and (r, q) distributed ions on the propagation properties of DA solitons, dressed solitons and energy of solitons in the presence of polarization force has been scrutinized.
