perturbation method for nonlinear differential equations

In this paper, the homotopy perturbation method (HPM) is extended to obtain analytical solutions for some nonlinear differential-difference equations (NDDEs). Ramesh Rao a,∗ a Department of Mathematics and Actuarial Science, B.S. The suggested algorithm is quite efficient and is practically well suited for use in these problems.

Despite the importance of obtaining the exact solution of nonlinear partial differential equations in physics and applied mathematics, there is still the daunting problem of finding new … Examples of one-dimensional and two-dimensional are presented to show the ability of the method for such equations. Key words:Homotopy perturbation method; Nonlinear integro-differential equations; Fractional differential equations INTRODUCTION Mathematical modeling of real-life problem usually results in functional equations, e.g. The resulting solutions are compared with those of the existing solutions obtained by employing the Adomian’s decomposition method. The modified algorithm provides approximate solutions in the form of convergent series with easily computable components. partial differential equations, integral and integro-differential equations, stochastic equations and others. We extend He's homotopy perturbation method (HPM) with a computerized symbolic computation to find approximate and exact solutions for nonlinear differential difference equations (DDEs) arising in physics. In this paper, we present a new method, a mixture of homotopy perturbation method and a new integral transform to solve some nonlinear partial differential equations. Perturbation iteration method has been recently constructed and it has been also proven that this technique is very effective for solving some nonlinear differential equations. From the calculation and its graphical representation it is clear that how the solution of the equation and its behavior depends on the initial conditions. Published by Scientific & Academic Publishing. On leave from Department of Mathematics, Mutah University, Jordan. Perturbative expansion polynomials are considered to obtain an infinite series solution. The effectiveness of this method is demonstrated by finding the exact solutions of the fractional equations proposed, for the special case … Recently, the generalized homotopy method (GHM) [1] was proposed as a generalization of the homotopy perturbation method (HPM). Abdur Rahman University, Chennai-600 048, TamilNadu, India.. Abstract. In this paper a new method called Elzaki transform homotopy perturbation method (ETHPM) is described to obtain the exact solution of nonlinear systems of partial differential equations. This … tively by using homotopy perturbation method. Book Description. Therefore, using as a guide the main idea of power series matching, be… The discretized modified Kortewegde Vries (mKdV) lattice equation and the discretized nonlinear Schrodinger equation are taken as examples to illustrate the validity and the great potential of the HPM in solving such NDDEs.
