Abstract:In this paper, we prove that the accelerated Adomian polynomials formula suggested by Adomian (Nonlinear Stochastic Systems: Theory and Applications to Physics, Kluwer, Dordrecht, 1989) and the accelerated formula suggested by El-Kalla (Int. J. Differ. Equs. Appl. 10(2):225-234, 2005; Appl. Math. E-Notes 7: [214][215][216][217][218][219][220][221] 2007) are identically the same. The Kalla-iterates exhibit the same faster convergence exhibited by Adomian's accelerated iterates with the additional advantage o… Show more
“…In the recent past, a lot of researchers [ 9 – 16 ] have expressed their interest in the study of ADM for various scientific models. Adomian [ 12 ] asserted that the ADM provides an efficient and computationally worthy method for generating approximate series solution for a large class of differential as well as integral equations.…”
We apply Adomian decomposition method (ADM) for obtaining approximate series solution of Urysohn integral equations. The ADM provides a direct recursive scheme for solving such problems approximately. The approximations of the solution are obtained in the form of series with easily calculable components. Furthermore, we also discuss the convergence and error analysis of the ADM. Moreover, three numerical examples are included to demonstrate the accuracy and applicability of the method.

We introduce an efficient recursive scheme based on Adomian decomposition
method (ADM) for solving nonlinear singular boundary value problems. This approach is based on a modification of the ADM; here we use all the boundary conditions to derive an integral equation before establishing the recursive scheme for the solution components. In fact, we develop the recursive scheme without any undetermined coefficients while computing the solution components. Unlike the classical ADM, the proposed method avoids solving a sequence of nonlinear algebraic or transcendental equations for the undetermined coefficients. The approximate solution is obtained in the form of series with easily calculable components. The uniqueness of the solution is discussed. The convergence and error
analysis of the proposed method are also established. The accuracy and reliability of the proposed method are examined by four numerical examples.
“…In this case it is difficult to integrate so, recursive (19) and (20) will be used in stead of (12) and (15). Using recursive (19) and (20), we can improve the accuracy of the solution not only by adding more terms to the solution series but also by increasing N in the recursive relation.…”

Table 5 shows the relative absolute error (RAE) for different values of x at N = 3 and N = 5 for the same partial sum S 5 .…”

“…Formula (6) has the advantage of absence of any derivative terms in the recursion, thereby allowing for ease of computations. Also, Formula (6) was used successfully in one dimensional problems [16,17] and in two dimensional problems [18,19] to study the convergence of ADM when applied to some classes of nonlinear equations. In this work, formula (6) is used in the convergence analysis and all the calculations of the numerical examples.…”
In this paper, a new technique for solving a class of nonlinear Boundary Value Problems (BVPs) is introduced. Convergence of the series solution obtained from the proposed technique is proved. Convergence analysis is reliable enough to estimate the maximum absolute truncated error of the series solution. Some numerical examples are introduced to verify the efficiency of the new technique.
