EVOLUTION OF SOLITARY WAVES IN MULTICOMPONENT PLASMAS

The nonlinear wave equation, derived by the augmentation of a Kadomtse v-Petviashvili (K-P) equation, discusses the evolution of soliton prop agation in plasma. We employed the recently developed new formalism of a modified simple wave solution technique to the nonlinear wave dynam ics for finding the soliton behaviour in plasma conceiving cold and wa rm electrons. Because of the new approach, the KP wave equation has be en transformed into an ordinary differential equation and finally solv ed by the Frobenius method in finding the nonlinear behaviours of the soliton propagation. The overall observations made by the straightforw ard method highlighted the various features of the solitary waves, som e of which were proven to be of theoretical and experimental interest. We, in the process of using the modified simple wave solution techniq ue, predicted the strength of the method in exhibiting the soliton dyn amics having collapse or explosion causeway by the presence of multi-t emperature electrons and it could be of interest by providing a better understanding in the laboratory and space plasmas.
