Özet:

 

The basic nonlinear equations describing the dynamics of a two component plasma consisting of cold positive ions and electrons obeying hybrid q- nonextensive non-thermal velocity distribution are examined through the use of modied PLK formalism and the reductive perturbation method and obtained the KdV equation for the lowest order term in the perturbation expansion. The method is further extended to include the contribution of higher order terms in the expansion; the evolution equation for the second order term is found to be the degenerate linearized  KdV equation with non- homogeneous term. Seekink the localized travelling wave solution  solitons  to these evolution equations we obtained the speed correction terms and the wave proles. Nu-merical results for the set of suitable parameters  Williams et. al. [23]  are shown inb the form of some graphs. The combined eect of nonextensive parameter  q  and the nonthermal parameter     on the soliton dynamics has also been studied.
