Sažetak

A generalized theory on the combined effects of ion-temperature, negative ions and higher-order corrections on ion-acoustic solitary waves in a multicomponent plasma containing warm, relativistic positive ions and negative ions, two-temperature and non-isothermal electrons has been made using reductive perturbation method. The basic set of fluid equations for the warm ion-fluids have been reduced to the renormalized Korteweg-de-Vries equation for the first-order perturbed potential and then a renormalized linear inhomogeneous equation for the second-order perturbed potential. Steady-state solutions of the coupled equations have been derived and eventually the solution representing the potential associated with the ion-acoustic wave has been obtained. The soliton profiles have been displayed graphically under various conditions.
