Controllability and constrained controllability for nonlocal Hilfer fractional differential systems with Clarke’s subdifferential

Journal of Inequalities and Applications, 2019
Sobolev-type nonlocal fractional differential systems with Clarke’s subdifferential are studied. Sufficient conditions for controllability and constrained controllability for Sobolev-type nonlocal fractional differential systems with Clarke’s ...

Global attractors for gradient flows in metric spaces [PDF]

, 2009
We develop the long-time analysis for gradient flow equations in metric spaces. In particular, we consider two notions of solutions for metric gradient flows, namely energy and generalized solutions.

Element‐Based Internal Variable Formulations for Finite Element Discretizations in FFT‐Based Homogenization Methods

International Journal for Numerical Methods in Engineering, Volume 126, Issue 21, 15 November 2025.
ABSTRACT Although finite elements were made available for FFT‐based computational homogenization methods, they are seldomly used for inelastic computations because traditionally the constitutive law is evaluated at each quadrature point of the element, making the storage of that many internal variables necessary, as well.

Derivatives of orbital function and an extension of Berezin-Gel’fand’s theorem

Special Matrices, 2016
A generalization of a result of Berezin and Gel’fand in the context of Eaton triples is given. The generalization and its proof are Lie-theoretic free and requires some basic knowledge of nonsmooth analysis.

A Note on the Existence and Optimal Control of Atangana–Baleanu Fractional Stochastic Integrodifferential System With Noninstantaneous Impulses

Optimal Control Applications and Methods, Volume 46, Issue 6, Page 2595-2611, November/December 2025.
Optimal Control of AB Caputo Fractional Stochastic Integrodifferential Control System with Noninstantaneous Impulses. ABSTRACT This study is concerned with the existence of mild solution and optimal control for the Atangana–Baleanu fractional stochastic integrodifferential system with noninstantaneous impulses in Hilbert spaces. We verify the existence

Unified gross substitutes and inverse isotonicity for equilibrium problems

Theoretical Economics, Volume 20, Issue 3, Page 941-971, July 2025.
We introduce a notion of substitutability for correspondences and establish a monotone comparative static result. More precisely, we introduce the notions of unified gross substitutes and nonreversingness and show that if Q:P⇉Q is a supply correspondence defined on a set of prices P, which is a sublattice of RN, and Q satisfies these two properties ...

Three nontrivial solutions for nonlocal anisotropic inclusions under nonresonance

Electronic Journal of Differential Equations, 2019
In this article, we study a pseudo-differential inclusion driven by a nonlocal anisotropic operator and a Clarke generalized subdifferential of a nonsmooth potential, which satisfies nonresonance conditions both at the origin and at infinity. We prove

Tropical analysis: With an application to indivisible goods

Theoretical Economics, Volume 20, Issue 3, Page 815-829, July 2025.
We establish the subgradient theorem for monotone correspondences: a monotone correspondence is equal to the subdifferential of a potential if and only if it is conservative, i.e., its integral along a closed path vanishes irrespective of the selection from the correspondence along the path.

Analysis and controllability of neutral integrodifferential systems governed by hemivariational inequalities with applications

Alexandria Engineering Journal
In this study, optimal and approximate control strategies are explored for a class of neutral integrodifferential systems. These systems are characterized by resolvent and history-dependent operators, operate within Hilbert spaces, and incorporate ...
