جوابهای سالیتونی در پلاسمای سه مؤلفه‌ای یون - الکترون- پوزیترون

  In this paper, we first study the conditions for the existence of the solitonic solutions in ion-electron-positron plasma. Then we investigate the effect of increasing positron on the solitonic wave properties, We also consider the time evolution of these waves in passing through the boundaries of two plasma with different positron densities and different positron-electron temperature ratios.
