Nonlinear ion-acoustic solitary waves in an electron-positron-ion plasma with relativistic positron beam |
(color online) The soliton solution is plotted with respect to the ion temperature σ along with variable positron concentration μb, where μb is 0.5, 0.7, and 0.9 for blue dotted, red dashed, and green bold lines, respectively, and other plasma parameters are c1 = 103, |
