Computation and application of Adomian polynomials
Abstract
In this paper, we make a simple introduction to the original established thought of Adomian decomposition method and the revision of this method. Then we give some concrete examples about the Adomian polynomials and use MATLAB to obtain the results of Adomian polynomials decomposition.
This paper is pided into four chapters. The first chapter is the introduction, we make a brief description about the historical background and development process of the Adomian decomposition method, and summarize some foreign scholars’ research results and application of this method.
Then, the power series method of differential equation is introduced. After that, we make a detailed introduction about the Adomian decomposition method and the application of it. And as for this method, we give a few examples. In the fourth chapter, the application of Adomian polynomials is realized by MATLAB programming. Finally, the summary of this paper is made.
Key words: Adomian decomposition method, the power series method, differential equation, Adomian polynomials
