چکیده
|
The propagation of nonlinear ion-acoustic waves in magnetized plasma consisting of cold ions, hot electrons and positrons has been studied. it is demonstrated that in the case of weak nonlinearity the ion-acoustic waves are described by the korteweg–de vries (k-dv) equation. the influence of finite positron density and temperature and external magnetic field on the properties of soliton-like waves is discussed.
