Jitendra Singh

摘要:

在这篇文章中,我们介绍了一种分析方法,即同伦分析变换方法(HATM),它是同伦分析方法(HAM)和拉普拉斯分解方法(LDM)的结合,与现有方法相比,该方法具有适用于线性和非线性分数阶微分方程的简单性和计算量小的优点,其最大的优点是可以求解分数阶非线性微分方程该方法不需要使用Adomian多项式和He多项式来计算非线性项,整个过程没有线性化和限制性假设。目前,同伦分析变换方法被用于求解时间分数阶Fokker-Planck方程和类似方程。HATM方法得到的级数解收敛很快,所得解与一些著名结果吻合良好

英文摘要:

In this article we introduce an analytical method, namely Homotopy Analysis Transform Method (HATM) which is a combination of Homotopy Analysis Method (HAM) and Laplace Decomposition Method (LDM).This scheme is simple to apply linear and nonlinear fractional differential equations and having less computational work in comparison of other exiting methods.The most useful advantage of this method is to solve the fractional nonlinear differential equation without using Adomian polynomials and He polynomials for the computation of nonlinear terms.The proposed method has no linearization and restrictive assumptions throughout the process.Presently homotopy analysis transform method is used to solve time fractional Fokker-Planck equation and similar equations.The series solution obtained by HATM converges very fast.A good agreement between the obtained solution and some well-known results has been demonstrated
