Finite time stability for Hadamard fractional-order systems

open access: yesAin Shams Engineering Journal
This paper examines the properties of finite-time stability (FTS) in the sense of Hadamard fractional-order systems. The investigation utilizes the Hadamard fractional derivative to formulate and analyze these systems, establishing FTS criteria based on ...

Continuous dependence of a solution for fractional order Cauchy-type problem

open access: yesPartial Differential Equations in Applied Mathematics, 2021
In this paper, we consider the generalized Cauchy-type problem involving Hilfer–Hadamard-type fractional derivative for the nonlinear fractional differential equations to study the continuous dependence of a solution on the general order under the ...

Diffusion of Characteristic Gases in Oil‐Immersed Transformer by Computational Fluid Dynamics Simulation and Experimental Verification

open access: yesHigh Voltage, EarlyView.
ABSTRACT The complex diffusion of characteristic gases within oil‐immersed transformers significantly influences the timeliness between the fault occurrence and gas detection. So far, the gas transport processes and spatio‐temporal distributions remain inadequately understood.

On solvability of BVP for a coupled Hadamard fractional systems involving fractional derivative impulses

open access: yesAIMS Mathematics, 2022
<abstract><p>Hadamard fractional calculus is one of the most important fractional calculus theories. Compared with a single Hadamard fractional order equation, Hadamard fractional differential equations have a more complex structure and a wide range of applications.

Refinements of some fractional integral inequalities involving extended convex functions and fractional Caputo derivatives

open access: yesJournal of Inequalities and Applications
This article examines famous fractional Hermite–Hadamard integral inequalities through the applications of fractional Caputo derivatives and extended convex functions. We develop modifications involving two known classical fractional extended versions of

Optimal Portfolio Choice With Cross‐Impact Propagators

open access: yesMathematical Finance, EarlyView.
ABSTRACT We consider a class of optimal portfolio choice problems in continuous time where the agent's transactions create both transient cross‐impact driven by a matrix‐valued Volterra propagator, as well as temporary price impact. We formulate this problem as the maximization of a revenue‐risk functional, where the agent also exploits available ...

Survey and new results on boundary-value problems of singular fractional differential equations with impulse effects

open access: yesElectronic Journal of Differential Equations, 2016
Firstly we prove existence and uniqueness of solutions of Cauchy problems of linear fractional differential equations (LFDEs) with two variable coefficients involving Caputo fractional derivative, Riemann-Liouville derivative, Caputo type Hadamard ...

An analogue of Leibniz’s rule for Hadamard derivatives and their application

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы
This paper explores new analogues of the Leibniz rule for Hadamard and Caputo–Hadamard fractional derivatives. Unlike classical derivatives, fractional ones have a strong nonlocal character, meaning that the value of the derivative at a given point ...

A Machine‐Learning Surrogate for Differentiable Phase Equilibrium Modeling of Mantle Rocks on a Planetary Scale

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Modeling processes within Earth's and other planetary bodies' mantle requires constraints from phase equilibrium to infer how changes in phase abundance and composition affect physical properties and geochemical processes. When applying such thermodynamic models on a planetary scale, performance becomes especially crucial.
