Abstract
The nonlinear propagation of cylindrical and spherical dust acoustic (DA) w aves in an unmagnetized dusty plasma is considered. By employing the reduct ive perturbation technique, a modified Korteweg-de Vries (K-dV) equation is derived from the dust continuity and momentum equations. Poisson's equatio n as well as Boltzmann electrons and ions. Numerical solutions of the modif ied K-dV equation are obtained. It has been found that the propagation char acteristics of the cylindrical and spherical DA solitary waves significantl y differ from those of one-dimensional DA solitary waves.
