General Fractional Vector Calculus [PDF]

open access: yesMathematics, 2021
A generalization of fractional vector calculus (FVC) as a self-consistent mathematical theory is proposed to take into account a general form of non-locality in kernels of fractional vector differential and integral operators.

Calculus of Variations with Classical and Fractional Derivatives [PDF]

open access: green, 2010
We give a proper fractional extension of the classical calculus of variations. Necessary optimality conditions of Euler-Lagrange type for variational problems containing both classical and fractional derivatives are proved. The fundamental problem of the

General Fractional Calculus in Multi-Dimensional Space: Riesz Form

open access: yesMathematics, 2023
An extension of the general fractional calculus (GFC) is proposed as a generalization of the Riesz fractional calculus, which was suggested by Marsel Riesz in 1949.

A Stochastic Fractional Calculus with Applications to Variational Principles

open access: yesFractal and Fractional, 2020
We introduce a stochastic fractional calculus. As an application, we present a stochastic fractional calculus of variations, which generalizes the fractional calculus of variations to stochastic processes.

An operational calculus formulation of fractional calculus with general analytic kernels

open access: yesElectronic Research Archive, 2022
Fractional calculus with analytic kernels provides a general setting of integral and derivative operators that can be connected to Riemann–Liouville fractional calculus via convergent infinite series.

Deformation of quantum mechanics in fractional-dimensional space [PDF]

open access: yes, 2001
A new kind of deformed calculus (the D-deformed calculus) that takes place in fractional-dimensional spaces is presented. The D-deformed calculus is shown to be an appropriate tool for treating fractional-dimensional systems in a simple way and quite ...

Enhancing the Mathematical Theory of Nabla Tempered Fractional Calculus: Several Useful Equations

open access: yesFractal and Fractional, 2023
Although many applications of fractional calculus have been reported in literature, modeling the physical world using this technique is still a challenge. One of the main difficulties in solving this problem is that the long memory property is necessary,

Review of Some Promising Fractional Physical Models [PDF]

open access: yes, 2015
Fractional dynamics is a field of study in physics and mechanics investigating the behavior of objects and systems that are characterized by power-law non-locality, power-law long-term memory or fractal properties by using integrations and ...
