چکیده

In this study, the numerical solution of a space-fractional parabolic partial differential equation was considered. The investigation made by focusing on diffusion (SFDE) problem. Note that symmetry an efficient approximation to SFDE based method is related compatibility discretization scheme and linear system solver. application one-dimensional, linear, unconditionally stable, implicit finite difference studied. general discretized using derivative Caputo with half-sweep scheme. formulated, formation coefficient matrix, which large sparse, shown. construction preconditioned also presented. This study’s contribution introduction successive over relaxation (HSPSOR) for SFDE-based equation. work extended use HSPSOR as time-fractional equation, has been presented in 5th North American International Conference industrial engineering operations management Detroit, Michigan, USA, 10–14 August 2020. current proposed several examples validate performance iterative solving fractional outcome illustrated competence solve proved superior standard approximation, full-sweep SOR (FSPSOR), terms computational complexity.

Approximation Solution of Fractional Partial Differential Equations by Neural Networks

Neural networks with radial basis functions method are used to solve a class of initial boundary value of fractional partial differential equations with variable coefficients on a finite domain. It takes the case where a left-handed or right-handed fractional spatial derivative may be present in the partial differential equations. Convergence of this method will be discussed in the paper. A num...

A fractional type of the Chebyshev polynomials for approximation of solution of linear fractional differential equations

In this paper we introduce a type of fractional-order polynomials based on the classical Chebyshev polynomials of the second kind (FCSs). Also we construct the operational matrix of fractional derivative of order $ gamma $ in the Caputo for FCSs and show that this matrix with the Tau method are utilized to reduce the solution of some fractional-order differential equations.

On the Numerical Solution of Fractional Parabolic Partial Differential Equations with the Dirichlet Condition

The first and second order of accuracy stable difference schemes for the numerical solution of the mixed problem for the fractional parabolic equation are presented. Stability and almost coercive stability estimates for the solution of these difference schemes are obtained. A procedure of modified Gauss elimination method is used for solving these difference schemes in the case of one-dimension...
