Modified numerical methods for fractional differential equations

T.), Alzaid, SS (Alzaid, Sara Salem) ; Alkahtani, BST (Alkahtani, Badr Saad . 2019

Abstract

A new modified numerical scheme is proposed. This idea is inspired through the general idea of the Lagrange and the Adams–Bashforth. We present the derivation of the general steps for a modified numerical scheme for an equation with two different fractional derivatives. We present an application of such method in a general nonlinear Cauchy problem. The application is presented to some fractional differential equations. Additionally we realized that when the non-integer order is one, the well-known multi-step-Adams–Bashforth numerical scheme for classical differential equations is recovered.

    Very recently, a new numerical scheme was introduced. The numerical scheme was developed using the Newton polynomial, as it is known to be more accurate than the Lagrange polynomial that was used…

    Based on the Newton polynomial which is accurate than the Lagrange polynomial, a new numerical scheme was introduced very recently by Atangana and Seda. Their method consisted in reverting a…

    A new concept of dynamical system of predator-prey model is presented in this paper. The model takes into account the memory of interaction between the prey and predator due to the inclusion of…
