چکیده

A high-order finite difference numerical scheme based on the compact operator is proposed in this paper for time-fractional partial integro-differential equations with a weakly singular kernel, where derivative term defined Riemann-Liouville sense. Here, stability and convergence of constructed are proved L∞ norm, accuracy order O(τ2+h4), τ h temporal spatial step sizes, respectively. The advantage that arbitrary parameters can be applied to achieve desired accuracy. Some examples presented support theoretical analysis.

A Meshless Method for Numerical Solution of Fractional Differential Equations

In this paper, a technique generally known as meshless numerical scheme for solving fractional dierential equations isconsidered. We approximate the exact solution by use of Radial Basis Function(RBF) collocation method. This techniqueplays an important role to reduce a fractional dierential equation to a system of equations. The numerical results demonstrate the accuracy and ability of this me...

Presentation of two models for the numerical analysis of fractional integro-differential equations and their comparison

In this paper, we exhibit two methods to numerically solve the fractional integro differential equations and then proceed to compare the results of their applications on different problems. For this purpose, at first shifted Jacobi polynomials are introduced and then operational matrices of the shifted Jacobi polynomials are stated. Then these equations are solved by two methods: Caputo fractio...

Homotopy analysis method for systems of fractional integro-differential equations

In this article, based on the homotopy analysis method (HAM), a new analytic technique is proposed to solve systems of fractional integro-differential equations. Comparing with the exact solution, the HAM provides us with a simple way to adjust and control the convergence region of the series solution by introducing an auxiliary parameter h . Four examples are tested using the proposed techniqu...
