# The homotopy index and partial differential equations

A new integral transform is a powerful tool for solving some differential equations. , Abstract and Applied Analysis, 2013. Some examples are given and comparisons are made. In this paper, the homotopy analysis method is applied to obtain the solution of nonlinear fractional partial differential equations. Numerical results shows that LHAM is easy to implement and when applied to solve accurate system of equations. The proposed iterative scheme finds the solution without any discretization, linearization or restrictive assumptions. 2 Center manifolds and their approximation. Modiﬁed least squares homotopy perturbation method for solving fractional partial differential equations 421/427 the existence of the solutions of a class of nonlinear fractional order partial differential equations with delay.

This work presents the application of the power series method (PSM) to find solutions of partial differential-algebraic equations (PDAEs). The homotopy index theory was developed by Charles Conley for two­ sided flows on compact spaces. Fractional partial differential equations and the method is called as generalized least square homotopy perturbations (GLSHP).

The numerical simulation of the proposed method has the sundry applications. The solution of HAM has improved the. In this article, we have established the homotopy analysis method (HAM) for solving a few partial differential equations arising in engineering. This method is a combined form of the Laplace transform method and the homotopy analysis method. The proposed method is coupling of the homotopy analysis method HAM and Laplace transform method [24-27]. The order of convergence and residuals are plotted. The He Homotopy Perturbation Method for. Ordinary differential equations FODEs as well as fractional partial differential equations FPDEs.

Solving Partial Differential Equations by Homotopy Perturbation. 5 Asymptotically linear systems. The Paperback of the The Homotopy Index and Partial Differential Equations by Krzysztof P. This permits direct applications to say, parabolic partial differential equations, or functional differential equations. The sufficient condition for convergence of the method is addressed. The results show also that the introduced method is a powerful tool for solving the fourth-order parabolic partial differential equations. From the result of the illustrative examples we conclude that the method is computationally efficient. , International Journal of Differential. In the present paper, the solutions of the hyperbolic partial differential equation with fractional time derivative of order α (1<α≤2) are obtained with the help of approximate analytical method of nonlinear problems called the homotopy analysis method. Some examples are presented to show the efficiency and simplicity of the method. Rybakowski: Libros en idiomas extranjeros Saltar al contenido principal Prueba Prime. Everal problems in sciences and engineering are modeled by linear and nonlinear partial differential equations. Keywords : Homotopy perturbation methods, Elzaki transform nonlinear partial differential equations. This method (the HPM), was originally proposed by He [9, 10].

The homotopy or Conley index, which provides an algebraic-topologi­ cal measure of an isolated invariant set, is defined to be the ho­ motopy type of the quotient space N /N, where is a certain 1 2 1.

[28] studied solutions of linear and nonlinear partial differential equations by using the homotopy perturbation Sumudu transform method (HPSTM). Solving nonlinear fractional differential equations using the homotopy analysis method Article in Numerical Methods for Partial Differential Equations 26(2):448 - 479 January 2009 with 1,929 Reads. The solutions of the studied models are calculated in the form of convergent series with easily computable components. In this article, the homotopy analysis method is applied to solve nonlinear fractional partial differential equations. The homotopy analysis method for partial differential equations of integer‐order is directly extended to derive explicit and numerical solutions of the fractional partial differential equations. In particular the proposed homotopy perturbation method (HPM) is tested on Helmholtz, Fisher s, Boussinesq, singular fourth-order partial differential equations, systems of partial differential equations and higher.

The aim of this Letter is to present an efficient and reliable treatment of the homotopy perturbation method (HPM) for nonlinear partial differential equations with fractional time derivative. Title = Exact solution for linear and nonlinear systems of PDES by homotopy-perturbation method, abstract = In this paper, the homotopy-perturbation method (HPM) proposed by J.

PDEs are used to formulate problems involving functions of several variables, and are either solved by hand, or used to create a computer model. Homotopy Analysis Method for Solving Non-linear Various Problem of Partial Differential Equations Zainab Mohammed Alwan Abbas* Asst. The Drinfeld-Sokolov (DS) system was ﬁrst intro- duced by Drinfeld and Sokolov and it is a system of nonlinear partial differential equations owner of the Lax pairs of a special form [1].

The book presents an extension, due to the present author, of Conley s homotopy index theory to certain (one-sided) semiflows on general (not necessarily locally compact) metric spaces.
