Comment on “Exact solutions of cylindrical and spherical dust ion acoustic waves” [Phys. Plasmas 10, 4162 (2003)]

Dusty plasmas have been found almost everywhere in the Universe. Sahu and Roychoudhury [Phys. Plasmas 10, 4162 (2003)] have done their interesting analytic work on the cylindrical dust ion-acoustic waves, without enough guidance to the readers on other existing analytic results. Such lack of guidanc... View More
