Normalized solutions of the critical Schrödinger–Bopp–Podolsky system with logarithmic nonlinearity
Transactions of the London Mathematical Society, Volume 12, Issue 1, December 2025.Abstract In this paper, we study the following critical Schrödinger–Bopp–Podolsky system driven by the p$p$‐Laplace operator and a logarithmic nonlinearity: −Δpu+V(εx)|u|p−2u+κϕu=λ|u|p−2u+ϑ|u|p−2ulog|u|p+|u|p*−2uinR3,−Δϕ+a2Δ2ϕ=4π2u2inR3.$$\begin{equation*} {\begin{cases} -\Delta _p u+\mathcal {V}(\varepsilon x)|u|^{p-2}u+\kappa \phi u=\lambda |u|^{p-2 ...

Identification of random coefficient latent utility models
Quantitative Economics, Volume 16, Issue 4, Page 1223-1265, November 2025.This paper provides nonparametric identification results for random coefficient distributions in perturbed utility models. We cover discrete choice and models of multiple purchases. We establish identification using variation in mean quantities. The results apply even when an analyst observes only aggregate demands but not whether goods are chosen ...

Multiple homoclinic solutions for a class of nonhomogeneous Hamiltonian systems
Boundary Value Problems, 2018 By introducing a new superquadratic condition, we obtain the existence of two nontrivial homoclinic solutions for a class of perturbed second order Hamiltonian systems which are obtained by the mountain pass theorem and Ekeland’s variational principle.

Professional perspectives on characteristics of legitimacy in court‐based mediation
Family Court Review, Volume 63, Issue 1, Page 138-154, January 2025.Abstract In Norway, court‐based mediation involves judges, lawyers, and psychologists working as a mediation team to bring settlement and avoid litigation. This article reports from a qualitative study with twenty‐two judges, psychologists, and lawyers from four district courts.

Vectorial form of Ekeland-type variational principle [PDF]
Fixed Point Theory and Applications, 2012 En este artículo, nos ocupamos de una forma vectorial del principio variacional de tipo Ekeland para un bioperador multivaluado cuyo dominio es un espacio métrico completo y su rango es un subconjunto de un espacio topológico de Hausdorff localmente convexo.

A variational principle and its connection with fixed point theory
, 1996 In this thesis, the following topics will be discussed; In chapter 2, a variational principle due to I. Ekeland (EVP) will be considered which deals with minimization of functions on a complete metric space; In chapter 3, the notion of completeness of a ...

On eigenvalues problems for the $p(x)$-Laplacian
, 2023 This paper studies nonlinear eigenvalues problems with a double non homogeneity governed by the $p(x)$-Laplacian operator, under the Dirichlet boundary condition on a bounded domain of $\mathbb{R}^N(N\geq2)$.

Time‐inconsistent contract theory
Mathematical Finance, Volume 34, Issue 3, Page 1022-1085, July 2024.Abstract This paper investigates the moral hazard problem in finite horizon with both continuous and lump‐sum payments, involving a time‐inconsistent sophisticated agent and a standard utility maximizer principal: Building upon the so‐called dynamic programming approach in Cvitanić et al.

Boundary Value ProblemsBy using the well-known mountain-pass theorem and Ekeland’s variational principle, we prove that there exist at least two fully nontrivial solutions for a ( p , q ) $(p,q)$ -Kirchhoff elliptic system with the Dirichlet boundary conditions and ...
