This paper dives into the study of ion-acoustic multi-solitons in plasma physics, utilizing PLK and Hirota's method for analysing the nonlinear evolution equations. It covers the composition of plasma, derived K-dV equations for solitons, and examines multi-soliton solutions such as two, three, four, and six-soliton interactions. Numerical observations highlight phase shifts due to density and temperature variations, with visualisations comparing isothermal and adiabatic plasmas. The...
