摘要：
By using the reductive perturbation theory, the Kadomstev-Petviashvili (KP) equation in unmagnetized dusty plasmas with variable dust charge, electrons with Boltzmann distribution and nonthermal ions, is derived and the propagation of nonlinear waves is analyzed. It is found that compressive and rarefactive solitons can be appeared. Amplitude of solitonic solutions of KP equation becomes diverges at the critical densities.
