Lie symmetry analysis for complex soliton solutions of coupled complex short pulse equation

Abstract

The current work is devoted for operating the Lie symmetry approach, to coupled complex short pulse equation. The method reduces the coupled complex short pulse equation to a system of ordinary differential equations with the help of suitable similarity transformations. Consequently, these systems of nonlinear ordinary differential equations under each subalgeras are solved for traveling wave solutions. Further, with the help of similarity variable, similarity solutions and traveling wave solutions of nonlinear ordinary differential equation, complex soliton solutions of the coupled complex short pulse equation are obtained which are in the form of sinh, cosh, sin and cos functions.

“…To simulate equations ( 1)-( 4), we reduce the equations into equations ( 11), ( 12), ( 14), and (15). Now, the next purpose is to solve non-linear ODE (11) and linear ODE (14).…”

“…us, there are many numerical techniques such as the similarity transformation (ST), homotopy analysis method (HAM), shooting method, Galerkin's finite element method (FEM), Runge-Kutta method, Runge-Kutta-Fehlberg method, and so on [1][2][3][4][5][6][7][8][9][10][11] which have been proposed for these types of NFTT models. ese types of models have been investigated in [14,15]. For such kind of models, hybrid and new techniques are welcome; those are nicely implemented with less computation cost.…”

New Localized and Periodic Solutions to a Korteweg–de Vries Equation with Power Law Nonlinearity: Applications to Some Plasma Models

“…Ordinary and partial differential equations have both been shown as effective tools for modeling natural phenomena in different branches of science and engineering. Therefore, it is important to be familiar with all recent analytical and numerical methods for modeling any natural and physical problem and solving it [1][2][3][4][5][6]. The following Korteweg-De Vries equation (KdV) equation is one of the most famous PDEs that has gained fame during the more than 50 years since its creation due to its ability for modeling many physical and natural phenomena in various fields of science [2,7] ∂ t ϕ + αϕ∂ x ϕ + β∂ 3 x ϕ = 0, (1) where ϕ ≡ ϕ(x, t) and α represents the coefficient of the nonlinear term, while β refers to the coefficient of the dispersion term.…”

“…[1][2][3][4][5][6][7] The main framework of evaluating fractional partial differential equations (FPDEs) is to search for exact and approximate solutions of problem, which has been a great task for mathematicians. In order to find exact and approximate solutions of PDEs, researchers projected distinct methods such as the sine-cosine method, tanh method, 8 reduced differential transform method, 9,10 homotopy analysis, 5,11 Lie symmetry analysis, [12][13][14][15][16][17][18][19] and variation iteration method. 20 Lie symmetry analysis 21 is powerful tool to generate explicit solution by reducing the given system of FPDEs into a nonlinear system of FODEs with Erdelyi-Kober (EK) fractional differential and integral operators.…”
