Application of the Lie Symmetry Analysis for second-order fractional differential equations
Obtaining analytical or numerical solution of fractional differential equations is one of the troublesome and challenging issue among mathematicians and engineers, specifically in recent years. The purpose of this paper Lie Symmetry method is developed to solve second-order fractional differential equations, based on conformable fractional derivative. Some numerical examples are presented to il...
متن کاملLie symmetry analysis for Kawahara-KdV equations
We introduce a new solution for Kawahara-KdV equations. The Lie group analysis is used to carry out the integration of this equations. The similarity reductions and exact solutions are obtained based on the optimal system method.
متن کاملDifferential Form Symmetry Analysis of Two Equations Cited by Fushchych
In Wilhelm Fushchych’s address, ”Ansatz ’95”, given to the first conference ”Symmetry in Nonlinear Mathematical Physics” [1], he listed many differential equations on which he and others had done some symmetry analysis. In this talk, the present author treats two of these equations rather extensively, using differential forms to find the symmetries, based on a method by F. B. Estabrook and hims...
