A qualitative study on generalized Caputo fractional integro-differential equations

Advances in Differential Equations, 2021
The aim of this article is to discuss the uniqueness and Ulam–Hyers stability of solutions for a nonlinear fractional integro-differential equation involving a generalized Caputo fractional operator. The used fractional operator is generated by iterating

Environmental Disclosure Under Mandatory Regulation in EU Listed Companies: An Institutional Analysis

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines corporate environmental reporting practices among listed companies in the European Union during the period 2018–2022, within the context of the Non‐Financial Reporting Directive (NFRD). To this end, an Environmental Disclosure Index (EDI) is constructed based on qualitative reporting items, and panel‐data models are ...

On the generalized fractional derivatives and their Caputo modification

The Journal of Nonlinear Sciences and Applications, 2017
Summary: In this manuscript, we define the generalized fractional derivative on \(AC^n_\gamma [a, b]\), the space of functions defined on \([a,b]\) such that \(\gamma^{n-1}f\in AC[a, b]\), where \(\gamma=x^{1-p}\frac{d}{dx}\). We present some of the properties of generalized fractional derivatives of these functions and then we define their Caputo ...

Generalized Monotone Method for Caputo Fractional Reaction-Diffusion Equation

International Journal of Advanced Research in Science, Communication and Technology, 2022
In this paper, our aim is to obtain the integral representation for the solution of non-linear Caputo reaction-diffusion equation of order q, where 0 < q < 1, in term of Green’s function. We have developed a generalized monotone method for non-linear weakly coupled Caputo reaction-diffusion equation.

Complex Dynamic Behaviour of Food Web Model with Generalized Fractional Operator

Mathematics, 2022
We apply a new generalized Caputo operator to investigate the dynamical behaviour of the non-integer food web model (FWM). This dynamical model has three population species and is nonlinear.

The M-Wright function in time-fractional diffusion processes: a tutorial survey

, 2010
In the present review we survey the properties of a transcendental function of the Wright type, nowadays known as M-Wright function, entering as a probability density in a relevant class of self-similar stochastic processes that we generally refer to as ...

On the analyzing of bifurcation properties of the one‐dimensional Mackey–Glass model by using a generalized approach

Mathematical Methods in the Applied Sciences, EarlyView.
The goal of this work is to look at how a nonlinear model describes hematopoiesis and its complexities utilizing commonly used techniques with historical and material links. Based on time delay, the Mackey–Glass model is explored in two instances. To offer a range, the relevance of the parameter impacting stability (bifurcation) is recorded.
