Differential equations with tempered Ψ-Caputo fractional derivative

open access: yesMathematical Modelling and Analysis, 2021
In this paper we define a new type of the fractional derivative, which we call tempered Ψ−Caputo fractional derivative. It is a generalization of the tempered Caputo fractional derivative and of the Ψ−Caputo fractional derivative.

Laplace Variational Iteration Method for Modified Fractional Derivatives with Non-singular Kernel [PDF]

open access: yesJournal of Applied and Computational Mechanics, 2020
A universal approach by Laplace transform to the variational iteration method for fractional derivatives with the nonsingular kernel is presented; in particular, the Caputo-Fabrizio fractional derivative and the Atangana-Baleanu fractional derivative ...

On Hilfer cotangent fractional derivative and a particular class of fractional problems

open access: yesAIMS Mathematics, 2023
In this work, a novel Hilfer cotangent fractional derivative is presented. This derivative combines the characteristics of the Riemann-Liouville cotangent fractional derivative and the Caputo cotangent fractional derivative.

Stochastic derivatives for fractional diffusions [PDF]

open access: yesThe Annals of Probability, 2007
In this paper, we introduce some fundamental notions related to the so-called stochastic derivatives with respect to a given $ $-field $\mathcal{Q}$. In our framework, we recall well-known results about Markov--Wiener diffusions. We then focus mainly on the case where $X$ is a fractional diffusion and where $\mathcal{Q}$ is the past, the future or the

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.

Fractional Coins and Fractional Derivatives [PDF]

open access: yesAbstract and Applied Analysis, 2013
This paper discusses the fundamentals of negative probabilities and fractional calculus. The historical evolution and the main mathematical concepts are discussed, and several analogies between the two apparently unrelated topics are established. Based on the new conceptual perspective, some experiments are performed shading new light into possible ...

A fractional spline collocation method for the fractional order logistic equation [PDF]

open access: yes, 2017
We construct a collocation method based on the fractional B-splines to solve a nonlinear differential problem that involves fractional derivative, i.e. the fractional order logistic equation.

No nonlocality. No fractional derivative [PDF]

open access: yesCommunications in Nonlinear Science and Numerical Simulation, 2018
The paper discusses the characteristic properties of fractional derivatives of non-integer order. It is known that derivatives of integer orders are determined by properties of differentiable functions only in an infinitely small neighborhood of the considered point.

Distributed-order fractional Cauchy problems on bounded domains [PDF]

open access: yes, 2009
In a fractional Cauchy problem, the usual first order time derivative is replaced by a fractional derivative. The fractional derivative models time delays in a diffusion process.
