Ion-acoustic solitary waves in two-temperature electron plasmas

By using the reductive perturbation technique, a modified Korteweg–deVries (KdV) equation aids in the study of the solitary wave solution in a nonisothermal two‐temperature electron plasma. The results indicate the solitary wave solution in the plasma with isothermal electrons, and finally a link with the solitons existing in both cases is made. Moreover, general comparisons and conclusions are made on the ion‐acoustic waves in the plasma with several ionic species and multiple electrons.
