Abstract

We investigate the existence of solutions for a sum-type fractional integro-differential problem via the Caputo differentiation. By using the shifted Legendre and Chebyshev polynomials, we provide a numerical method for finding solutions for the problem. In this way, we give some examples to illustrate our results.

Summary

Introduction

In , Reinermann investigated some problems by using approximate fixed point property ([ ]). There has been published some work about different fractional integro-differential equations by using Chebyshev polynomials ([ , ] and [ ]) or by using Legendre wavelets ([ – ] and [ ]). In this paper by using an approximate fixed point result and the shifted Legendre and Chebyshev polynomials, we investigate the existence of solutions for a sum-type fractional integro-differential problem. The fractional differential equation cDqx(t) = v(t) has a solution in the form x(t) = Iqv(t) + c + c t + · · · + cn– tn– .
