Existence of Solution for Two Classes of Quasilinear Systems Defined on a Nonreflexive Orlicz–Sobolev Spaces

Mathematical Methods in the Applied Sciences, Volume 49, Issue 12, Page 13324-13360, August 2026.
ABSTRACT This paper proves the existence of nontrivial solution for two classes of quasilinear systems of the type −ΔΦ1u=Fu(x,u,v)+λRu(x,u,v)inΩ−ΔΦ2v=−Fv(x,u,v)−λRv(x,u,v)inΩu=v=0on∂Ω$$ \left\{\begin{array}{l}\hfill -{\Delta}_{\Phi_1}u={F}_u\left(x,u,v\right)+\lambda {R}_u\left(x,u,v\right)\kern0.1832424242424242em \mathrm{in}\kern0.3em \Omega ...

Existence and multiplicity of solutions for a differential inclusion problem involving the p(x)-Laplacian

Electronic Journal of Differential Equations, 2010
In this article we consider the differential inclusion $$displaylines{ -hbox{div}(| abla u|^{p(x)-2} abla u)in partial F(x,u) quadhbox{in }Omega,cr u=0 quad hbox{on }partial Omega }$$ which involves the $p(x)$-Laplacian.

The Weak Core, Partition‐Based Universal Stability, and Their Risk Associations Through A Partial Order

Naval Research Logistics (NRL), Volume 73, Issue 5, Page 810-835, August 2026.
ABSTRACT We are concerned with the stability of a transferable‐utility cooperative (TU) game. First, the concept of core can be weakened so that the blocking of changes is limited to only those with multilateral backings. This principle of consensual blocking, as well as the traditional core‐defining one of unilateral blocking and one straddling in ...

Multiplicity of solutions for non-homogeneous Neumann problems in Orlicz-Sobolev spaces

Electronic Journal of Differential Equations, 2017
This article concerns the existence of non-trivial weak solutions for a class of non-homogeneous Neumann problems. The approach is through variational methods and critical point theory in Orlicz-Sobolev spaces.

On Neumann hemivariational inequalities

Abstract and Applied Analysis, 2002
We derive a nontrivial solution for a Neumann noncoercive hemivariational inequality using the critical point theory for locally Lipschitz functionals. We use the Mountain-Pass theorem due to Chang (1981).

A revision of the genus Armeria (Plumbaginaceae) in peninsular Italy and Sicily through an integrative taxonomic approach

TAXON, Volume 75, Issue 4, August 2026.
Abstract The genus Armeria in peninsular Italy has been affected by taxonomic ambiguity for more than a century due to high morphological variability. We present a comprehensive revision of peninsular Italian and Sicilian Armeria species, using an integrated taxonomic approach that combines molecular phylogeny, plant and seed morphometrics, and ...

Vertical Correlation Lengths as a Tool for Quantifying Profiling Capabilities in the Planetary Boundary Layer and Troposphere and Defining Future Requirements

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract The planetary boundary layer (PBL) is the portion of the troposphere that is directly influenced by the presence of the Earth's surface. The thermodynamic structure of this layer exhibits a wide variety of characteristics across the globe. In 2018 the National Academies of Sciences, Engineering, and Medicine Space Studies Board recommended ...

Multiple solutions for Schrodinger-Maxwell systems with unbounded and decaying radial potentials

Electronic Journal of Differential Equations, 2014
This article concerns the nonlinear Schrodinger-Maxwell system $$\displaylines{ -\Delta u +V(|x|)u +Q(|x|)\phi u=Q(|x|) f(u),\quad \hbox{in } \mathbb{R}^3\cr -\Delta \phi =Q(|x|) u^{2}, \quad \hbox{in } \mathbb{R}^3 }$$ where V and Q are unbounded ...

Multiple Solutions for a Critical Steklov Kirchhoff Equation

Fractal and Fractional
In the present work, we study some existing results related to a new class of Steklov p(x)-Kirchhoff problems with critical exponents. More precisely, we propose and prove some properties of the associated energy functional. In the first existence result,

Multiple Solutions for Nonhomogeneous Neumann Differential Inclusion Problems by the p(x)-Laplacian

The Scientific World Journal, 2013
A class of nonlinear Neumann problems driven by p(x)-Laplacian with a nonsmooth locally Lipschitz potential (hemivariational inequality) was considered. The approach used in this paper is the variational method for locally Lipschitz functions.
