A Robust Higher-Order Scheme for Fractional Delay Differential Equations Involving Caputo Derivative

Abstract

This article considers nonlinear fractional delay differential equations involving Caputo�s fractional derivative of order�. We focus on designing a robust numerical algorithm of order�. To achieve this, we developed a higher-order interpolation-based approximation for Caputo�s derivative, which enables us to construct a robust numerical scheme for the considered problem. Furthermore, we discuss the stability and error analysis of the proposed higher-order scheme. Finally, numerous examples, including real-life applications, are evaluated to demonstrate the computational efficiency of the proposed algorithm.
