A computationally efficient fractional predictor corrector approach involving the Mittag Leffler kernel

Abstract

In this paper, based on Newton interpolation we have proposed a numerical scheme of predictor-corrector type in order to solve fractional differential equations with the fractional derivative involving the Mittag-Leffler function. We have added an auxiliary midpoint in each sub-interval, this allows us to use a piecewise quadratic Newton interpolation to derive the corrector scheme. The derivation of the schemes for the midpoint and the predictor is done by means of a piecewise linear Newton interpolation. We present some illustrative examples for initial value problems that involve fractional derivatives in the sense of Atangana-Baleanu. The results of numerical experiments show that the proposed scheme is a powerful technique to handle fractional differential equations with nonlinear terms that involve operators of Atangana-Baleanu type. Moreover, the proposed method significantly improves the numerical accuracy in comparison with other methods.
