Solitary waves of the Kadomstev–Petviashvili equation in warm dusty plasma with variable dust charge, two temperature ion and nonthermal electron

The propagation of nonlinear waves in warm dusty plasmas with variable dust charge, two temperature ion and nonthermal electron is studied. By using the reductive perturbation theory, the Kadomstev–Petviashivili (KP) equation is derived. Existence of rarefactive and compressive solitons is analyzed.
