A new perspective for the Quintic B-spline collocation method via the Lie-Trotter splitting algorithm to solitary wave solutions of the GEW equation

A hybrid method utilizing the collocation technique with B-splines and Lie-Trotter splitting algorithm applied for 3 model problems which include a single solitary wave, two solitary wave interaction, and a Maxwellian initial condition is designed for getting the approximate solutions for the generalized equal width (GEW) equation. Initially, the considered problem has been split into 2 sub-equations as linear Ut = ^ A(U) and nonlinear Ut = ^B (U)in the terms of time. After, numerical schemes have been constructed for these sub-equations utilizing the nite element method (FEM) together with quintic B-splines. Lie-Trotter splitting technique ^ Ao^B has been used to generate approximate solutions of the main equation. The stability analysis of acquired numerical schemes has been examined by the Von-Neumann method. Also, the error norms L2 and L1 with mass, energy, and momentum conservation constants I1, I2, and I3, respectively are calculated to illustrate how perfect solutions this new algorithm applied to the problem generates and the ones produced are compared with those in the literature. These new results exhibit that the algorithm presented in this paper is more accurate and successful,and easily applicable to other non-linear partial di erential equations (PDEs) as the present equation.
