We study the asymptotic behavior of solutions of a nonlinear differential
equation.
Using Bihari's integral inequality, we obtain sufficient conditions for all of
continuable solutions to be asymptotic.

In this paper ,we study asymptotic properties of solutions of the following
third – order differential equations with -P Laplacian.
In the sequel,it is assumed that all solutions of the equation are

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.
This research studies the distributive solutions for some partial
differential equations of second order.
We study specially the distributive solutions for Laplas equation,
Heat equation, wave equations and schrodinger equation.

In this paper, we study the oscillation and nonoscillation theorems
for second order nonlinear difference equations.
By using some important of definitions and main concepts in
oscillation, in addition for lemmas, we introduce examples
illustrating the relevance of the theorems discussed.
Most of mathematical physics problems can be translated into solve one
partial differential equation or more with specific initial conditions and
boundary conditions. This is called the boundary value problem for the
differential equations.
