The Use of Generalized Laguerre Polynomials in Spectral Methods for Solving Fractional Delay Differential Equations

Abstract: In this paper, an efficient numerical method for solving the fractional delay differential equations (FDDEs) is considered. The fractional derivative is described in the Caputo sense. The proposed method is based on the derived approximate formula of the Laguerre polynomials. The properties of Laguerre polynomials are utilized to reduce FDDEs to a linear or nonlinear system of algebraic equations. Special attention is given to study the error and the convergence analysis of the proposed method. Several numeric… Show more

“…Most FDEs do not have exact solutions, so approximate and numerical techniques [2][3][4][5][6][7][8][9][10] must be used. Recently, several numerical methods to solve FDEs have been given, such as variational iteration method [8], homotopy perturbation method [11,12], Adomian decomposition method [13], homotopy analysis method [7], collocation method [14][15][16][17][18][19][20][21][22][23][24] and finite difference method (FDM) [25,26]. We describe some necessary definitions and mathematical preliminaries of the fractional calculus theory required for our subsequent development.…”
