Symmetries and Exact Solutions of Some Systems of Nonlinear Partial Differential Equations by Lie Classical Method

Abstract

The objective of this thesis entitled, “ Symmetries and Exact Solutions of Some Systems of Nonlinear Partial Differential Equations by Lie Classical Methods”, is to obtain the Lie symmetries and the exact solutions of nonlinear partial differential equations or their systems, which represent some of the important physical phenomenon. The nonlinear phenomena are encountered in a variety of situations in physics as well as in other natural applied sciences. Most of these phenomena are governed by nonlinear partial differential equations.
