Abstract- In this paper, the instability of Dust-Ion-Acoustic waves in the presence of the dust charge fluctuations in a collisionless unmagnetized dusty plasmas is investigated by kinetic theory. We consider Maxwellian distribution for plasma particles in the equilibrium and negatively charged dust grains. It is shown that dust-ion-acoustic wave instability can exist even if the drift speeds of the plasma particles are equal to zero. The results of kinetic theory are compared with those of fluid theory.
Keywords: Dust Charge Fluctuation, Dust-Ion-Acoustic waves, kinetic theory
