Abstract
The effect of linear ion Landau damping on weakly nonlinear as well as weakly dispersive low-frequency waves in a dusty plasma is investigated. The standard perturbative approach leads to the Korteweg–de Vries
(KdV) equation with a linear Landau damping term for the
dynamics of the low-frequency nonlinear wave. Landau
damping causes the wave amplitude to decay with time and
the dust charge variation enhances the damping rate.
