Semi-Analytical Solutions of Nonlinear Equation Modelling Reaction in a Dispersive Medium

Abstract

This study explores the semi-analytical solutions of the third-order dispersive equation with reaction (Fisher-like) term. Recently,the proposed problem has been exactly solved in the literature. Additionally, the semi-analytical solutions are needed to understandthe sensitivity of homotopy based methods in solving the proposed reaction-dispersion equation. Using symbolic computation withcarefully chosen perturbation parameters, the semi-analytical solutions are compared with the exact solutions, in order to show theefficiency of homotopy and Padé techniques. Obtained solutions, which can play key role in modelling reaction in a dispersive medium,are illustrated and discussed.
