Improved Soliton Solutions of Generalized Fifth Order Time-Fractional KdV Models: Laplace Transform with Homotopy Perturbation Algorithm

The main purpose of this research is to propose a new methodology observe class time-fractional generalized fifth-order Korteweg–de Vries equations. Laplace transform along with homotopy perturbation algorithm utilized for the solution and analysis in current study. This extended technique provides improved convergent series solutions through symbolic computation. proposed applied Sawada–Kotera, Ito, Lax’s, Kaup–Kupershmidt models, which are induced from KdV equation. For validity purposes, obtained existing results at integral orders compared. Convergence was also performed by computing errors different values fractional domain. Dynamic behavior parameter studied graphically. Simulations affirm dominance terms accuracy fewer computations as compared other available schemes KdVs. Hence, projected can be more advanced models physics engineering.
