An Expansion Formula with Higher-Order Derivatives for Fractional Operators of Variable Order [PDF]

open access: yesThe Scientific World Journal, 2013
We obtain approximation formulas for fractional integrals and derivatives of Riemann-Liouville and Marchaud types with a variable fractional order. The approximations involve integer-order derivatives only. An estimation for the error is given.

Fractional integrals, derivatives and integral equations with weighted Takagi–Landsberg functions

open access: diamondNonlinear Analysis: Modelling and Control, 2020
In this paper, we find fractional Riemann–Liouville derivatives for the Takagi–Landsberg functions. Moreover, we introduce their generalizations called weighted Takagi–Landsberg functions, which have arbitrary bounded coefficients in the expansion under Schauder basis.

Fractional Integrals and Derivatives: “True” versus “False”

open access: yesMathematics, 2023
Within the last few years, many of the efforts of the fractional calculus (FC) community have been directed towards clarifying the nature and essential properties of the operators known as fractional integrals and derivatives [...]

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.
