Attractors and upper semicontinuity for an extensible beam with nonlocal structural damping
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 2, February 2026.Abstract We analyze the asymptotic behavior of a class of extensible beam models governed by a nonlocal structural damping mechanism of the form φ(El)(−Δ)βut$\varphi (E_l)(-\Delta)^{\beta }u_t$, where β∈λ=(0,1]$\beta \in \lambda =(0,1]$. The coefficient φ$\varphi$ is a degenerate C1$C^{1}$‐function depending on the linear energy El$E_l$ of the system ...

Debt Ceilings With Fiscal Intransparency and Imperfect Electoral Accountability
International Economic Review, Volume 67, Issue 1, Page 97-125, February 2026.ABSTRACT We study optimal debt ceilings in a political‐agency model with uncertainty about both policymaker type (benevolent or selfish) and economic state (good or bad). Elections generate disciplining and selection effects that differ across pooling, hybrid, and separating equilibria induced by different ceilings.

Semicontinuity of capacity under pointed intrinsic flat convergence [PDF]
, 2022 The concept of the capacity of a compact set in $\mathbb R^n$ generalizes readily to noncompact Riemannian manifolds and, with more substantial work, to metric spaces (where multiple natural definitions of capacity are possible).

Nonemptiness of the Alpha‐Core
Journal of Public Economic Theory, Volume 28, Issue 1, February 2026.ABSTRACT We prove nonemptiness of the α $\alpha $‐core for balanced games with nonordered preferences, extending and generalizing in several aspects the results of Scarf (1971), Border (1984), Florenzano (1989), Yannelis (1991b), and Kajii (1992). In particular, we answer an open question in Kajii (1992) regarding the applicability of the nonemptiness ...

Non-upper-semicontinuity of algebraic dimension for families of compact complex manifolds
, 2010 In this note we show that in a certain subfamily of the Kuranishi family of any half Inoue surface the algebraic dimensions of the fibers jump downwards at special points of the parameter space showing that the upper semicontinuity of algebraic ...

Efficiency in Pure‐Exchange Economies With Risk‐Averse Monetary Utilities
Mathematical Finance, Volume 36, Issue 1, Page 99-117, January 2026.ABSTRACT We study Pareto efficiency in a pure‐exchange economy where agents' preferences are represented by risk‐averse monetary utilities. These coincide with law‐invariant monetary utilities, and they can be shown to correspond to the class of monotone, (quasi‐)concave, Schur concave, and translation‐invariant utility functionals. This covers a large

New Continuity Structures for Fuzzy Multifunctions via υ‐Fuzzy γ‐Open Sets and Fuzzy Ideals
Journal of Mathematics, Volume 2026, Issue 1, 2026.This study introduces several new classes of continuity for fuzzy multifunctions based on υ‐fuzzy γ‐open sets, namely fuzzy upper γ‐continuity (F+γ‐continuity), fuzzy lower γ‐continuity (F−γ‐continuity), fuzzy upper almost γ‐continuity (F+Aγ‐continuity), fuzzy lower almost γ‐continuity (F−Aγ‐continuity), fuzzy upper weakly γ‐continuity (F+Wγ‐continuity)

Fuzzy‐Fractional Modeling and Analysis of Tobacco Smoking Dynamics via He–Laplace–Carson Framework
Journal of Mathematics, Volume 2026, Issue 1, 2026.This study develops a fuzzy‐fractional nonlinear tobacco smoking model by incorporating triangular fuzzy numbers and Caputo fractional derivative. The He–Laplace–Carson algorithm is used to solve and analyze the uncertainties and memory dependent effects involved in potential smokers, mild smokers, regular smokers, and quit smokers.
