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).

Methodological Frameworks for Computational Electrocatalysis: From Theory to Practice

Small Methods, Volume 10, Issue 5, 9 March 2026.
Computational modeling is widely used to investigate electrocatalytic reactions, yet accurately describing electrochemical interfaces remains challenging. This review outlines theoretical and computational strategies, based on density functional theory, to model reaction thermodynamics, solvation effects, applied bias, and kinetics.

Amendment Thresholds and Voting Rules in Debt Contracts

Journal of Accounting Research, Volume 64, Issue 1, Page 181-227, March 2026.
ABSTRACT Most loan contracts in the United States contain a provision for lender voting rules. We study the optimal voting rule that allows lenders to waive a covenant violation. When lenders have heterogeneous preferences, lenient voting rules increase the probability of waivers that allow inefficient investments.

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.

Numerical Study of a Nonlocal Nonlinear Schrödinger Equation (MMT Model)

Studies in Applied Mathematics, Volume 156, Issue 3, March 2026.
ABSTRACT In this paper, we study a nonlocal nonlinear Schrödinger equation (MMT model). We investigate the effect of the nonlocal operator appearing in the nonlinearity on the long‐term behavior of solutions, and we identify the conditions under which the solutions of the Cauchy problem associated with this equation are bounded globally in time in the ...

Sand Transport Rate and Turbulent Fluctuation in Aeolian Transportation Over the Gobi Surface Under Extremely High Winds

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract There are no theoretical formulas that can accurately predict the sand transport rate (Qm) over the Gobi surface. We report herein high‐frequency field observations of wind‐blown sand processes over the Gobi surface under extremely high winds in eastern Xinjiang, China. The results reveal that the power‐law exponent of the scaling relationship

Forecasting and uncertainty estimation of the Shahroud River discharge using long short‐term memory and Kolmogorov–Arnold networks

Vadose Zone Journal, Volume 25, Issue 1, January/February 2026.
Abstract Forecasting river discharge plays a vital role in water resources management, flood control, and also the safe design of hydraulic structures. Due to the complexity and nonlinearity of hydrological processes, in this research, long short‐term memory (LSTM) and Kolmogorov–Arnold networks (KANs) have been used to predict discharge and estimate ...

Existence and Multiplicity Results of Homoclinic Solutions for the DNLS Equations with Unbounded Potentials

Abstract and Applied Analysis, 2012
A class of difference equations which include discrete nonlinear Schrödinger equations as special cases are considered. New sufficient conditions of the existence and multiplicity results of homoclinic solutions for the difference equations are obtained ...
