Abstract

A variety of closed-form solutions such as multiple-front wave, kink wave, waves interaction, curve-shaped multisoliton, parabolic and stationary wave solutions have been obtained by using invariance of the concerned potential Kadomtsev–Petviashvili (PKP) equation under the one-parameter Lie group of transformations. Lie symmetry transformations have been applied to generate various forms of invariant solutions of the PKP equation. The solutions provide extensive rich physical structure due to the existence of various arbitrary constants and functions. Results have been traced in context to spatiotemporal dynamics. Dynamic behavior of the results have been analyzed in terms of various wave propagations. Numerical simulation has been performed to obtain appropriate visual appearance of the traced solutions. The nature of solutions is investigated both analytically and physically through their evolutionary profiles by considering adequate choices of arbitrary functions and constants.
