Lessons on State and Local Income Taxes From the Twenty‐First Century and Challenges for the Future

Public Budgeting &Finance, EarlyView.
Abstract I survey recent research on subnational income tax policy, arguing that a defining feature is geography. Geographic boundaries limit the power of subnational governments to tax people and activities. The article discusses where income should be taxed and the effects of these tax rules on the interjurisdictional mobility of people and jobs.

The relationship between intergenerational mobility and equality of opportunity

The Scandinavian Journal of Economics, EarlyView.
Abstract Among economists, the analysis of social mobility and the role of parental background is largely carried out in two separate strands of research. The intergenerational mobility literature estimates parent–child persistence in some outcome of interest, such as income.

Mental Health Emergency Department Visits and Hospitalizations Among Alabama Publicly Insured Youth During COVID‐19

Psychiatric Research and Clinical Practice, EarlyView.
Objective Increases in the proportion of pediatric emergency department (ED) visits due to mental illness (MI) or intentional self‐harm (ISH) in early months of the COVID‐19 pandemic have been documented. Less is known about hospitalizations, or trends during later months of the pandemic.

On the additive image of zeroth persistent homology

Transactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.
Abstract For a category X$X$ and a finite field F$F$, we study the additive image of the functor H0(−;F)∗:rep(X,Top)→rep(X,VectF)$\operatorname{H}_0(-;F)_* \colon \operatorname{rep}(X, \mathbf {Top}) \rightarrow \operatorname{rep}(X, \mathbf {Vect}_F)$, or equivalently, of the free functor rep(X,Set)→rep(X,VectF)$\operatorname{rep}(X, \mathbf {Set ...

Context‐free graphs and their transition groups

Transactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.
Abstract Starting from context‐free inverse graphs, we introduce a new class of groups and study their structural properties. We establish closure properties, show that their coword problems are context‐free, analyze torsion elements, and realize them as subgroups of the asynchronous rational group.

Surface subgroups for cocompact lattices of isometries of H2n$\mathbb {H}^{2n}$

Journal of Topology, Volume 19, Issue 3, September 2026.
Abstract We prove the existence of surface subgroups within any cocompact lattice Γ$\Gamma$ in SO(2n,1)$\mathrm{SO}(2n,1)$ for n⩾2$n\geqslant 2$. This result addresses the cases missing from the work of Hamenstädt in 2015, who constructed surface subgroups in cocompact lattices for all other rank‐1 simple Lie groups of noncompact type.

Comparative Case Study of Small‐Scale Fish Processing for Local Seafood Supply

Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
ABSTRACT This study examines the cost feasibility of local seafood processing as a market diversification strategy for small‐scale aquaculture producers in the US Midwest. It addresses a gap in the literature by moving beyond commercial processing and mass marketing of processed seafood to assess the cost profitability of niche local fish processing ...

Invariant Measure and Universality of the 2D Yang–Mills Langevin Dynamic

Communications on Pure and Applied Mathematics, Volume 79, Issue 8, Page 1973-2102, August 2026.
ABSTRACT We prove that the Yang–Mills (YM) measure for the trivial principal bundle over the two‐dimensional torus, with any connected, compact structure group, is invariant for the associated renormalised Langevin dynamic. Our argument relies on a combination of regularity structures, lattice gauge‐fixing and Bourgain's method for invariant measures ...

Policy Choices and Individuals' Attitudes From the Perspective of Imaginary Future Generations—A Discussion Experiment With City Officials on Carbon Neutrality

FUTURES &FORESIGHT SCIENCE, Volume 8, Issue 2, August 2026.
ABSTRACT In this study, we demonstrate the effects of adopting “imaginary future generations (IFGs),” which has been proven to be effective for generating futurability in individuals, on policy choices and individual attitudes toward environmentally friendly behavior.

Common Neighborhood Energy of the Non-Commuting Graphs and Commuting Graphs Associated with Dihedral and Generalized Quaternion Groups

Mathematics
This paper explores the common neighborhood energy (ECN(Γ)) of graphs derived from the dihedral group D2n and generalized quaternion group Q4n, specifically the non-commuting graph (NCM-graph) and the commuting graph (CM-graph).
