Approximate and Closed-Form Solutions of Newell-Whitehead-Segel Equations via Modified Conformable Shehu Transform Decomposition Method

In this study, we introduced a novel scheme to attain approximate and closed-form solutions of conformable Newell-Whitehead-Segel (NWS) equations, which belong the most consequential amplitude equations in physics. The Shehu transform (CST) Adomian decomposition method (ADM) are combined proposed method. We call it (CSDM). To assess efficiency consistency recommended method, demonstrate 2D 3D graphs as well numerical simulations derived solutions. As result, CSDM demonstrates that is useful simple mathematical tool for getting exact analytical linear-nonlinear fractional partial differential (PDEs) given kind. convergence absolute error analysis series also offered.
