In this paper, the Combined Laplace Transform-Adomian Decomposition Method is used to solve nth-order integro-differential equations. The results show that the method is very simple and effective.

The main aim of this article is to generalize the Legendre operational matrix to the fractional derivatives and implemented it to solve the nonlinear multi-order fractional differential equations. In this approach, a truncated Legendre series together with the Legendre operational matrix of fractional derivatives are used. The main characteristic behind the approach using this technique is that...

In this paper, we propose a new modified recursion scheme for the approximate solution of higher-order, multipoint, nonlinear boundary value problems with higher-order Robin-type boundary conditions by the Adomian decomposition method. Our new approach utilizes all of the boundary conditions to derive an equivalent nonlinear Fredholm-Volterra integral equation before establishing the new modifi...

In this research, three numerical methods, namely the variational iteration method, Adomian decomposition and homotopy analysis method are considered to achieve an approximate solution for a third-order time-fractional partial differential Equation (TFPDE). The equation is obtained from classical (FW) by replacing integer-order time derivative with Caputo fractional of order η=(0,1] variable co...

Nonlinear coupled partial differential equations are physical problems since it makes the unnecessary very important in a variety of scientific fields. They arise linearization, perturbation problem being solved. in large number of mathematical and engineering In this study, the ADM is extended to problems, especially in fluid mechanics, solid state analytic-numeric simulation for strictly hype...

The current article studied a nonlinear transmission of the nerve impulse model, Fitzhugh–Nagumo (FN) in conformable fractional form with an efficient analytical approach based on combination Sumudu transform and Adomian decomposition method. Convergence analysis error were also carried out Banach fixed point theory. We provided some examples to support our results. results obtained revealed th...
