A Local Estimate for the Maximal Function in Lebesgue Spaces with EXP‐Type Exponents

open access: yesJournal of Function Spaces, Volume 2015, Issue 1, 2015., 2015
It is proven that if 1 ≤ p(·) < ∞ in a bounded domain Ω⊂Rn and if p(·) ∈ EXPa(Ω) for some a > 0, then given f ∈ Lp(·)(Ω), the Hardy‐Littlewood maximal function of f, Mf, is such that p(·)log(Mf) ∈ EXPa/(a+1)(Ω). Because a/(a + 1) < 1, the thesis is slightly weaker than (Mf) λp(·) ∈ L1(Ω) for some λ > 0. The assumption that p(·) ∈ EXPa(Ω) for some a > 0

The roles of multinational enterprises in governing the sustainability of global supply chains

open access: yesInternational Journal of Management Reviews, Volume 28, Issue 3, July 2026.
Abstract An extensive but fragmented body of research shows that multinational enterprises (MNEs) engage with multiple sustainability rules in global supply chains (GSCs) spanning the private, social and public governance sectors. MNEs perform diverse roles by either shaping or complying with these rules.

Stability and Convergence of Solutions to Volterra Integral Equations on Time Scales

open access: yesDiscrete Dynamics in Nature and Society, Volume 2015, Issue 1, 2015., 2015
We consider Volterra integral equations on time scales and present our study about the long time behavior of their solutions. We provide sufficient conditions for the stability and investigate the convergence properties when the kernel of the equations vanishes at infinity.

Disarticulations in Naples: Cultural political ecology, the green transition, and labour unrest at a Whirlpool factory

open access: yesTransactions of the Institute of British Geographers, Volume 51, Issue 1, March 2026.
Abstract This article develops a cultural political ecology approach to disarticulations and labour unrest. The reference point for analysis is a struggle at a Whirlpool factory in Naples that the company announced would close in 2019, six months after signing an agreement with the Italian government, including a multi‐million investment plan.

Maximum Principles for Discrete and Semidiscrete Reaction‐Diffusion Equation

open access: yesDiscrete Dynamics in Nature and Society, Volume 2015, Issue 1, 2015., 2015
We study reaction‐diffusion equations with a general reaction function f on one‐dimensional lattices with continuous or discrete time ux′ (or Δtux)=k(ux-1-2ux+ux+1)+f(ux), x∈Z. We prove weak and strong maximum and minimum principles for corresponding initial‐boundary value problems.

Bifurcation for indefinite‐weighted p$p$‐Laplacian problems with slightly subcritical nonlinearity

open access: yesMathematische Nachrichten, Volume 297, Issue 11, Page 3982-4002, November 2024.
Abstract We study a superlinear elliptic boundary value problem involving the p$p$‐Laplacian operator, with changing sign weights. The problem has positive solutions bifurcating from the trivial solution set at the two principal eigenvalues of the corresponding linear weighted boundary value problem.

Interval Oscillation Criteria for Second‐Order Nonlinear Forced Dynamic Equations with Damping on Time Scales

open access: yesAbstract and Applied Analysis, Volume 2013, Issue 1, 2013., 2013
By using the Riccati transformation technique and constructing a class of Philos‐type functions on time scales, we establish some new interval oscillation criteria for the second‐order damped nonlinear dynamic equations with forced term of the form (r(t)xΔ(t)) Δ + p(t)xΔσ(t) + q(t)(xσ(t)) α = F(t, xσ(t)) on a time scale 𝕋 which is unbounded, where α is

Uniqueness of Positive Solutions to Non-Local Problems of Brézis–Oswald Type Involving Hardy Potentials

open access: yesMathematics
The aim of this paper is to demonstrate the existence of a unique positive solution to non-local fractional p-Laplacian equations of the Brézis–Oswald type involving Hardy potentials.

Why diffusion‐based preconditioning of Richards equation works: Spectral analysis and computational experiments at very large scale

open access: yesNumerical Linear Algebra with Applications, Volume 31, Issue 1, January 2024.
Abstract We consider here a cell‐centered finite difference approximation of the Richards equation in three dimensions, averaging for interface values the hydraulic conductivity K=K(p)$$ K=K(p) $$, a highly nonlinear function, by arithmetic, upstream and harmonic means.
