On the nonextensivity contributions in collisional plasma damping waves

Abstract

Waves characteristic of solitary damped forms in plasmas fluids contain two polarity ions, nonextensivity positrons and electrons have been studied. The damped equation of Kadomtsev–Petviashvili (DKP) equation has been derived. The critical plasma density condition of DKP equation is introduced for parameters concerning Earth's ionosphere. The impacts of densities, ionic mass ratio, index of nonextensivity and frequencies of collision parameters on the nonlinear structures have been investigated. It is mentioned that the consequences obtained from this study may be applied in space plasmas.
