Abstract differential equations and Caputo fractional derivative

open access: yesSemigroup Forum, 2022
In this work I consider the abstract Cauchy problems with Caputo fractional time derivative of order $ \in(0,1]$, and discuss the continuity of the respective solutions regarding the parameter $ $. I also present a study about the continuity of the Mittag-Leffler families of operators (for $ \in(0,1]$), induced by sectorial operators.

On Caputo $k$ -Fractional Derivatives and Associated Inequalities

open access: yesIEEE Access, 2019
This paper studies the k-fractional analogue of the Caputo fractional derivatives, their properties, and applications. A convolution of two functions instead of the product is analyzed by means of Caputo k-fractional derivatives.

On a New Modification of the Erdélyi–Kober Fractional Derivative

open access: yesFractal and Fractional, 2021
In this paper, we introduce a new Caputo-type modification of the Erdélyi–Kober fractional derivative. We pay attention to how to formulate representations of Erdélyi–Kober fractional integral and derivatives operators.

A fractional model of cancer-immune system with Caputo and Caputo–Fabrizio derivatives [PDF]

open access: yesThe European Physical Journal Plus, 2021
Recently, it is important to try to understand diseases with large mortality rates worldwide, such as infectious disease and cancer. For this reason, mathematical modeling can be used to comment on diseases that adversely affect all people. So, this paper discuss mathematical model presented for the first time that examines the interaction between ...

Taylor’s Formula for Generalized Weighted Fractional Derivatives with Nonsingular Kernels

open access: yesAxioms, 2022
We prove a new Taylor’s theorem for generalized weighted fractional calculus with nonsingular kernels. The proof is based on the establishment of new relations for nth-weighted generalized fractional integrals and derivatives. As an application, new mean

Lyapunov Functions to Caputo Fractional Neural Networks with Time-Varying Delays

open access: yesAxioms, 2018
One of the main properties of solutions of nonlinear Caputo fractional neural networks is stability and often the direct Lyapunov method is used to study stability properties (usually these Lyapunov functions do not depend on the time variable).

Caputo–Hadamard Fractional Derivatives of Variable Order [PDF]

open access: yesNumerical Functional Analysis and Optimization, 2016
ABSTRACTIn this article, we present three types of Caputo–Hadamard derivatives of variable fractional order and study the relations between them. An approximation formula for each fractional operator, using integer-order derivatives only, is obtained and an estimation for the error is given.

Generalised Fractional Evolution Equations of Caputo Type [PDF]

open access: yes, 2017
This paper is devoted to the study of generalised time-fractional evolution equations involving Caputo type derivatives. Using analytical methods and probabilistic arguments we obtain well-posedness results and stochastic representations for the ...
