Lie groups and Lie Symmetry Analysis and Travelling Wave Solutions Of Equal width Wave equation

We can create a deep connection between the world’s industry and technologies and economic research institutes by using differential equations. We obtained the power series solution and the travelling wave solutions of equal width wave equation by using the lie symmetry method the fundamental idea behind the symmetry transformation method is that it reduces one independent variables in a system of PDEs by utilizing lie symmetries and surface invariance condition. We first obtained the infinitesimals and commutation table with the help of maple software. Lie symmetry transformation method (STM) has been applied on EWW equation and converted it into various nonlinear ODEs. Then, the tanh method and the power series method have been applied for solving the reduced nonlinear ordinary differential equations (ODEs). Convergence of the power series solutions has also been shown.
