Fractional Integrals and Derivatives: Mapping Properties [PDF]

open access: yesFractional Calculus and Applied Analysis, 2016
This is a fundamental survey of numerous results devoted to mapping properties of diverse modifications of fractional integrals (in one and many dimensions) in a variety of function spaces. The main focus is on fractional integrals of variable order and function spaces with variable exponents.

Calculus of variations with fractional derivatives and fractional integrals [PDF]

open access: yesApplied Mathematics Letters, 2009
We prove Euler-Lagrange fractional equations and sufficient optimality conditions for problems of the calculus of variations with functionals containing both fractional derivatives and fractional integrals in the sense of Riemann-Liouville.

Desiderata for Fractional Derivatives and Integrals [PDF]

open access: yesMathematics, 2019
The purpose of this brief article is to initiate discussions in this special issue by proposing desiderata for calling an operator a fractional derivative or a fractional integral.

Numerical Approaches to Fractional Integrals and Derivatives: A Review

open access: yesMathematics, 2020
Fractional calculus, albeit a synonym of fractional integrals and derivatives which have two main characteristics—singularity and nonlocality—has attracted increasing interest due to its potential applications in the real world.

Approximation of fractional integrals by means of derivatives

open access: yesComputers and Mathematics With Applications, 2012
We obtain a new decomposition of the Riemann-Liouville operators of fractional integration as a series involving derivatives (of integer order). The new formulas are valid for functions of class $C^n$, $n \in \mathbb{N}$, and allow us to develop suitable numerical approximations with known estimations for the error.

Nabla Fractional Derivative and Fractional Integral on Time Scales [PDF]

open access: yesAxioms, 2021
In this paper, we introduce the nabla fractional derivative and fractional integral on time scales in the Riemann–Liouville sense. We also introduce the nabla fractional derivative in Grünwald–Letnikov sense. Some of the basic properties and theorems related to nabla fractional calculus are discussed.

Hermite-Hadamard, Trapezoid and Midpoint Type Inequalities Involving Generalized Fractional Integrals for Convex Functions [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2023
We first construct new Hermite-Hadamard type inequalities which include generalized fractional integrals for convex functions by using an operator which generates some significant fractional integrals such as Riemann-Liouville fractional and the Hadamard
