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.

Chromatic Polynomials and Cryptographic Hashing on WIP‐Quasigroup Structures
Journal of Mathematics, Volume 2026, Issue 1, 2026.Cryptographic hash functions are indispensable for today’s information security because they secure data integrity, authentication and encrypted storage. Recently, graph‐theoretic constructions have acquired interest in the design of hash functions because of their noteworthy sensitivity to structural alterations and rich combinatorial structure ...

Topological Aspects of Quadratic Graphs and M‐Polynomials Utilizing Classes of Finite Quasigroups
Journal of Mathematics, Volume 2026, Issue 1, 2026.Material science, drug design and toxicology studies, which relate a molecule’s structure to its numerous properties and activities, are studied with the use of the topological index. Graphs with finite algebraic structure find extensive applications in fields such as mathematics, elliptic curve cryptography, physics, robotics and information theory ...

Mantle Structure Beneath the Greater Alpine Region From Teleseismic Full P‐Waveform Inversion
Journal of Geophysical Research: Solid Earth, Volume 130, Issue 11, November 2025.Abstract AlpArray data were employed to infer a new mantle model of the Alps from teleseismic full P‐waveform inversion. It features hybrid numerical forward modeling in the time domain, compression of wavefields by Fourier transform at selected frequencies, the use of frequency domain waveform sensitivity kernels and a multi‐scale approach by ...

Contribution of Thermal Tides to Venus Upper Cloud‐Layer Superrotation
AGU Advances, Volume 6, Issue 5, October 2025.Abstract Venus's cloud‐layer superrotation, characterized by equatorial zonal winds of ∼100 m/s, is sustained by the atmospheric angular momentum (AM) transport induced by atmospheric waves, especially thermal tides, and meridional circulation. However, the overall patterns of thermal tides and their individual components' contribution to superrotation

Bargaining Foundations for Price Taking in Matching Markets
International Economic Review, Volume 66, Issue 4, Page 1561-1575, October 2025.ABSTRACT Agents make noncontractible investments before bargaining over who matches with whom and their terms of trade. An agent is a price taker when her investments do not change her potential partners' payoffs. This incentivizes socially optimal investments.

An Aggregative Games Approach to Merger Analysis in Multiproduct‐Firm Oligopoly
The RAND Journal of Economics, Volume 56, Issue 3, Page 233-250, Autumn (Fall) 2025.ABSTRACT Using an aggregative games approach, we analyze horizontal mergers in a model of multiproduct‐firm price competition with CES and logit demand, allowing for arbitrary firm and product heterogeneity. We provide conditions under which a merger raises consumer surplus, and establish the dynamic optimality of a myopic, consumer‐surplus‐based ...

Pressure‐driven flow in thin straight tubes of non‐uniform cross‐section
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 105, Issue 8, August 2025.Abstract We analyze stationary Stokes flow of a Navier–Stokes fluid in a thin tube with a variable cross‐section. The objective is to derive a simplified model by examining the asymptotic behavior as the tube's thickness approaches zero. The flow is driven by a pressure gradient between the inlet and outlet, which is modeled by prescribing the normal ...
