In this paper, a new space-time spectral algorithm is constructed to solve the generalized Hirota-Satsuma coupled Korteweg-de Vries GHS-C-KdV system of time-fractional order. The present algorithm consists of applying the collocationspectral method in conjunction with the operational matrix of fractional derivative for the double Jacobi polynomials, which will be employed as a basis function for the spectral solution. The main characteristic behind this approach is that such problems will reduce to those of solving algebraic systems of equations that greatly simplifying the problem. For ensuring the accuracy and efficiency of the presented algorithm, we apply it to find the approximate solutions of two specific problems, namely, a homogeneous form of the GHS-C-KdV system and a inhomogeneous GHS-C-KdV system. Key words: Generalized Hirota-Satsuma coupled KdV system; spectral colocation method; fractional Caputo derivative; operational matrix; Jacobi-Gauss quadrature.. INTRODUCTION Finding effective and robust analytical and numerical techniques for solving fractional differential equations FDEs has become the focus of many research studies during the past years. Several techniques such as the Laplace transform method [, 2], the fractional sub-equation method [3], the Block pulse operational matrix method [4], the iterative method [5], the finite element method [6], the homotopy analysis method [7], the implicit compact difference scheme [8], collocation method [9 8] and other effective methods have been put forward [9 3]. Spectral methods [3 38] have been proposed and developed to numerically solve fractional ordinary and partial differential equations, see [39 44]. In addition to this, the spectral methods have been employed in conjunction with operational matrices techniques of fractional derivatives to spectrally solve various types of fractional Romanian Journal of Physics 62, 5 27 v.2.*27.3.3#85329b

On the other hand, the operational matrix of fractional integrals is constructed and used coupling with spectral methods to solve FDEs [5]. Bhrawy [5] proposed a new operational matrix for the pseudospectral method for numerically solve the one-dimensional fractional sub-diffusion equations based on double Jacobi polynomials; moreover, the method was developed based on the triple Jacobi polynomials to handle the two dimensional version of such problem. However, in Ref. [52] Bhrawy proposed and developed a new pseudospectral technique for achieving a high accurate approximate solution of time-space fractional partial differential equation PDE, in which, the Legendre Gauss-Lobatto collocation approximation is adapted for spatial discretization and the Chebyshev Gauss-Radau collocation approximation is employed for temporal discretization. The generalized Hirota-Satsuma coupled Korteweg-de Vries GHS-C-KdV system has been firstly introduced by Wu et al. [53]. This equation can be used to describe the interaction of two long waves with different dispersion relations. Ganji et al. [54] introduced the GHS-C-KdV system with time-fractional order and applied the homotopy perturpation method for introducing solitary wave solutions for it, while in [55], the variational iteration method was applied for the same purpose. Recently, the authors of Ref. [56] applied the improved fractional sub-equation method to find an analytical solution of the GHS-C-KdV system with time-fractional order. The objective of this paper is to introduce a new approximate solution of the GHS-C-KdV system with time-fractional order ν ux,t t ν = 3 ux,t 2 3 3ux,t ux,t + 3 vx, twx, t + qx,t, ν vx,t t ν = 3 vx,t 3 + 3ux,t vx,t + rx,t, ν wx,t t ν = 3 wx,t 3 + 3ux,t wx,t + sx,t, subject to the initial conditions: ux, = ψ x, vx, = ψ 2 x, wx, = ψ 3 x, < x L, 2 and boundary conditions: u,t = f t, v,t = f 2 t, w,t = f 3 t, u x L,t = g t, v x L,t = g 2 t, w x L,t = g 3 t, u xx L,t = h t, v xx L,t = h 2 t, w xx L,t = h 3 t, < t τ, 3 where ν, < ν is a real constant, and qx,t, rx,t and sx,t are the source functions. The introduced technique consists of expanding the functions ux,t, vx,t, c RJP 62, id:5-27 v.2.*27.3.3#85329b

Then, we apply the pseudospectral technique to reduce the problem to an algebraic system of equations. Several illustrative examples are presented to ensure the high accuracy and the power of the present method. This article is organized as follows. In Sec. 2, some definitions and notations are presented. In Sec. 3, the operational matrix and the pseudo-spectral method are implemented to propose a new approximate solution for the time-fractional GHS-C- KdV system -3. In Sec. 4, the high accuracy and validity of the present scheme are reported through two illustrative examples. The conclusions are given in Sec PRELIMINARIES AND NOTATION This Section reports two fractional definitions and an overview of Jacobi polynomials. Definition..

THE NUMERICAL SCHEME In the current Section, we apply the collocation-spectral method in combination with the operational matrix of fractional derivative with the shifted Jacobi polynomials as basis functions to approximate the solution of the GHS-C-KdV system of time-fractional order with the initial conditions 2 and the boundary conditions 3. Making use of the initial conditions 2, the problem -3 may be rewritten as in the form ν ux,t t ν + ux, ψ x = 3 ux,t ν vx,t t ν + vx, ψ 2 x = 3 vx,t 3 ν wx,t t ν + wx, ψ 3 x = 3 wx,t 3 3ux,t ux,t vx, twx, t + qx,t, + 3ux,t vx,t + 3ux,t wx,t + rx,t, + sx,t, subject to the conditions 3. Now, we approximate ux,t, vx,t, wx,t, qx,t, rx,t, and sx,t by the shifted Jacobi polynomials as u M,N x,t T τ,mtu L,N x, w M,N x,t T τ,mtw L,N x, r M,N x,t T τ,mtr L,N x, v M,N x,t T τ,mtv L,N x, q M,N x,t T τ,mtq L,N x, s M,N x,t T τ,mts L,N x, where the unknown coefficients U, V, and W, which are M + N + matrices will be evaluated to determine the approximate solutions, while Q, R, and S are known matrices and may be obtained from Q = [q ij ] R M N, R = [r ij ] R M N, S = [s ij ] R M N, 5 6 c RJP 62, id:5-27 v.2.*27.3.3#85329b

We shall investigate the approximation solution and convergence order with different orders by using the introduced method. Let us define the convergence order CO by CO = logerrorn /errorn 2, 2 logn 2 /N where errorn denotes the error corresponding to polynomial degree N. In this section the CPU time is performed on a HP laptop with the following configuration: Intel Core, i7-374 CPU, 2.7 GHz, and 8 Gb RAM. 4.. HOMOGENEOUS PROBLEM As the first example, we consider the following homogeneous problem: ν ux,t t ν = 3 ux,t 2 3 3ux,t ux,t + 3 vx, twx, t, ν vx,t t ν = 3 vx,t 3 + 3ux,t vx,t, ν wx,t t ν = 3 wx,t 3 + 3ux,t wx,t, subject to the initial conditions: 22 ux, = γ 2k2 + 2k 2 tanh 2 kx, 3 vx, = 4k2 c γ + k 2 3c 2 + 4k2 γ + k 2 tanhkx, 3c wx, = c + c tanhkx, where γ, k, c, and c are arbitrary constants. The exact solution at ν = is ux,t = γ 2k2 3 vx,t = 4k2 c γ + k 2 3c 2 + 2k 2 tanh 2 kx + γt, wx,t = c + c tanhkx + γt. + 4k2 γ + k 2 tanhkx + γt, 3c Ganji et al. [54] introduced this problem and applied the HPM for approximating its solution, while in Ref. [55], the authors applied the FIM for the same purpose. In order to show that our technique is more accurate than HPM [54] and FIM [55], we compare our results with those obtained in Refs. [54] and [55].
