The effect of a non-thermal ion velocity distribution is studied on linear and nonlinear dust-acoustic waves in an unmagnetized three component dusty plasma. For the linear theory, electrons are Boltzmann distributed, ions ...

Nonlinear low frequency electrostatic waves which arise from the coupling between two linear modes, viz., the dust-acoustic and dust-cyclotron waves, are studied in a magnetized dusty plasma comprising Boltzmann electrons, ...
