“…2 where s, n, g, u are infinitesimal transformations of Lie group variables (independent and dependent variables) that have to be determined later. Following the algorithm of Lie [14], we aim to determine the functions s, n, g, u and hence the form of the vector field v. Usually, the determining equations of the functions s, n, g, u are over-determined set of linear partial differential equations. After lengthy calculations and many algebraic manipulations, the set of equations can be solved and yield…”
