Abstract :
The nonlinear evolution of acoustic wave in unmagnetized dusty plasma in which electrons are completely depleted (corresponding to F Saturn ring) was shown to obey the Davey-Stewartson I equation which admits so called dromion solutions. The importance of these two dimensional localized solutions for recent satellite observations of wave structures in the day side polar cap regions was discussed.
