On the inequality of weierstrass for nonlocal functionals

open access: yesJournal of Inequalities and Applications, 2001
The aim of this paper is to consider the problem of extremum of the nonlocal functional, which depends on a function and its derivative with respect to at several values of .

System-conditioned reparameterization of the SCAN functional for accurate bandgaps: from analytical constraints to machine learning [PDF]

open access: yesnpj Computational Materials
This work investigates how reparametrizing the Strongly Constrained and Appropriately Normed (SCAN) exchange-correlation (XC) functional within density functional theory affects predictions of the electronic bandgap (E g ) for solids.

Fixed-point topology meets fractal memory: a Kutumba-stabilized framework for nonlocal fractal–fractional dynamics [PDF]

open access: yesScientific Reports
This paper presents an innovative synthesis of generalised fixed-point theory, advanced topological degree methodologies, and high-order computational frameworks for memory-driven dynamical systems. We expand contraction principles in complete metric and

BV Functions and Nonlocal Functionals in Metric Measure Spaces

open access: yesJournal of Geometric Analysis
AbstractWe study the asymptotic behavior of three classes of nonlocal functionals in complete metric spaces equipped with a doubling measure and supporting a Poincaré inequality. We show that the limits of these nonlocal functionals are comparable to the total variation $$\Vert Df\Vert (\Omega )$$ ‖

Fast All-Electron Hybrid Functionals and Their Application to Rare-Earth Iron Garnets

open access: yesFrontiers in Materials, 2022
Virtual materials design requires not only the simulation of a huge number of systems, but also of systems with ever larger sizes and through increasingly accurate models of the electronic structure.

Factorization method for solving nonlocal boundary value problems in Banach space [PDF]

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2021
This article deals with the factorization and solution of nonlocal boundary value problems in a Banach space of the abstract form B1 u = A u - S Φ( u )- G Ψ(A0 u) = f, u ∈ D (B1) , where A, A0 are linear abstract operators, S, G are vectors of functions,

Ground state solution for a class of supercritical nonlocal equations with variable exponent

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2021
In this paper, we obtain the existence of positive critical point with least energy for a class of functionals involving nonlocal and supercritical variable exponent nonlinearities by applying the variational method and approximation techniques. We apply

Strong maximum principles for implicit parabolic functional-differential problems together with nonlocal inequalities with functionals [PDF]

open access: yesOpuscula Mathematica, 2009
The aim of the paper is to give strong maximum principles for implicit parabolic functional-differential problems together with nonlocal inequalities with functionals in relatively arbitrary \((n+1)\)-dimensional time-space sets more general than the ...
