Sažetak

Propagation of a finite-amplitude ion-acoustic solitary wave in a weakly-relativistic plasma consisting of cold ions and warm electrons of two different temperatures have been studied analytically. Sufficient and necessary conditions for the existence of ion-acoustic solitons in such a plasma are obtained from which it is observed that both the relativistic effect and the two-temperature electrons have important role for the formation of the soliton. Critical values for the soliton amplitude and its velocity are numerically estimated for different values of the concentration of two-temperature electrons and relativistic stream velocity.
