Abstract :
The nonlinear propagation of dust-ion-acoustic (DIA) waves in a dusty electronegative plasma (consisting of inertialess electrons, nonthermal positive ions, inertial negative ions, and extremely massive charge fluctuating dust) has been investigated by employing the reductive perturbation technique. It has been shown that the effects of nonthermal ions and dust charge fluctuation (associated with Maxwellian electrons and nonthermal positive ions) have significantly modified the basic features of nonlinear DIA waves. The results of this paper would be useful in understanding the basic nonlinear feature of DIA wave propagation in laboratory and space dusty electronegative plasmas.
