A numerical method for finding solution of the distributed‐order time‐fractional forced Korteweg–de Vries equation including the Caputo fractional derivative [PDF]

open access: yesMathematical Methods in the Applied Sciences, 2020
In this paper, for the first time, the distributed‐order time‐fractional forced Korteweg–de Vries equation is studied. We use a numerical method based on the shifted Legendre operational matrix of distributed‐order fractional derivative with Tau method to find approximate solution of distributed‐order forced Korteweg–de Vries equation.

On a System of Equations with General Fractional Derivatives Arising in Diffusion Theory

open access: yesFractal and Fractional, 2023
A novel two-compartment model for drug release was formulated. The general fractional derivatives of a specific type and distributed order were used in the formulation. Earlier used models in pharmacokinetics with fractional derivatives follow as special

Jacobi Spectral Galerkin Method for Distributed-Order Fractional Rayleigh–Stokes Problem for a Generalized Second Grade Fluid

open access: yesFrontiers in Physics, 2020
Distributed-order fractional differential operators provide a powerful tool for mathematical modeling of multiscale multiphysics processes, where the differential orders are distributed over a range of values rather than being just a fixed fraction.

A Plea for the Integration of Fractional Differential Systems: The Initial Value Problem

open access: yesFractal and Fractional, 2022
The usual approach to the integration of fractional order initial value problems is based on the Caputo derivative, whose initial conditions are used to formulate the classical integral equation.

Delay-Dependent Stability Criterion of Caputo Fractional Neural Networks with Distributed Delay

open access: yesDiscrete Dynamics in Nature and Society, 2014
This paper is concerned with the finite-time stability of Caputo fractional neural networks with distributed delay. The factors of such systems including Caputo’s fractional derivative and distributed delay are taken into account synchronously.
