In this article, we propose a powerful method called
homotopy perturbation method (HPM) for obtaining the
analytical solutions for an non-linear system of partial
differential equations. We begin this article by apply HPM
method for an important models of linear and non-linear
partial differential equations.
We aim in this research to study the existence and uniqueness of strong solution for
initial-boundary values problem for a semi-linear wave equation with the nonlinear
boundary dissipation, by transforming it to a Cauchy problem with second order operator
differential equations in Hilbert space. Therefore, we transform it, using Green's formula
for a triple of Hilbert spaces.
In this article, powerful approximate analytical
methods, called Adomian decomposition method and
variational iteration method are introduced and applied to
obtaining the approximate analytical solutions for an
important models of linear and non-
linear partial differential
equations such as ( nonlinear Klein Gordon equation -
nonlinear wave equation - linear telegraph equation -
nonlinear diffusion convection equation ) .
The studied examples are used to reveal that those methods are
very effective and convenient for solving linear and nonlinear
partial differential equations .
Numerical results and comparisons with the exact solution are
included to show validity, ability, accuracy, strength and
effectiveness of those techniques.
