Weak Solutions for a Class of Nonlocal Singular Problems Over the Nehari Manifold

Mathematical Methods in the Applied Sciences, Volume 49, Issue 11, Page 12360-12378, 30 July 2026.
ABSTRACT In this paper, we consider a nonlocal model of dilatant non‐Newtonian fluid with a Dirichlet boundary condition. By using the Nehari manifold and fibering map methods, we obtain the existence of at least two weak solutions, with sign information.

Advancing Aquifer Characterization Through the Integration of Satellite Geodesy, Geomechanics, and Bayesian Inference

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Unsustainable rates of groundwater (GW) depletion make GW management a priority. Effective GW management is hindered by the uncertainty in the predictions of aquifer models, but the increase of geodetic surface deformation data can improve aquifer characterization.

The nonlocal bistable equation: Stationary solutions on a bounded interval

Electronic Journal of Differential Equations, 2002
We discuss instability and existence issues for the nonlocal bistable equation. This model arises as the Euler-Lagrange equation of a nonlocal, van der Waals type functional.

The periodicity of the Euler-Lagrange equation

, 2004
Thesis manuscript (University of Łódź, 2004) proving periodicity of the solutions of the Euler-Lagrange equation for autonomous, separable Lagrange functions L(x, ẋ) = g(ẋ) + h(x) with strictly convex g and strictly concave h, by a step-by-step reconstruction of the Euler-Lagrange curves.

Wild solutions to scalar Euler-Lagrange equations

Transactions of the American Mathematical Society
We study very weak solutions to scalar Euler-Lagrange equations associated with quadratic convex functionals. We investigate whether W 1
