The homotopy analysis method (HAM) aims to solve nonlinear ordinary differential equations and partial differential equations analytically. The method distinguishes itself from other analytical methods in the following four aspects. First, it is a series expansion method but it is independent of small physical parameters at all. Thus it is applicable for not only weakly but also strongly nonlinear problems. Secondly, the HAM is a unified method for the Lyapunov artificial small parameter method, the delta expansion method and the Adomian decomposition method. Thirdly, the HAM provides a simple way to ensure the convergence of the solution; also it provides freedom to choose the base function of the desired solution. Fourthly, the HAM can be combined with many other mathematical methods—such as numerical methods, series expansion methods, integral transform methods and so forth.
The method was devised by Shi-Jun Liao in 1992.[1]
