The transverse singular complex

Greg Friedman, Anibal M. Medina-Mardones, Dev Sinha ยท 2026

Let $M$ be a smooth manifold without boundary and let $\mathcal{T}$ be a countable collection of manifolds with corners, each equipped with a smooth map to $M$. We show that the singular simplicial seโ€ฆ

Rational characteristic classes of bundles with fibre a product of spheres

Jan McGarry-Furriol ยท 2026

We prove the existence of many non-trivial characteristic classes of smooth oriented bundles with fibre a product $ S^{n}\times S^{n} $ of odd-dimensional spheres. We do so by proving injectivity of tโ€ฆ

A Ring structure on the Class of Combinatorial Games

Harry Altman, Paolo Lipparini ยท 2026

J. Conway defined useful operations on the Class of combinatorial games and also introduced a notion of equivalence between games. Conway showed that, under his equivalence, games form a Group. Howeveโ€ฆ

$\mathbb{K}$-framings and $\mathbb{K}$-quadratic forms on surfaces

Nariya Kawazumi ยท 2026

We introduce the notions of $\mathbb{K}$-framings, based $\mathbb{K}$-framings and relative $\mathbb{K}$-framings of a compact connected oriented surface $\Sigma$ for any commutative ring $\mathbb{K}$โ€ฆ

Torus Equivariant Cohomology for the $\Delta$-Springer Fiber

Raymond Chou ยท 2026

We define a torus $U \subset T = (\mathbb{C}^\times)^K$ which acts on the $\Delta$-Springer varieties $Y_{n,\lambda,s}$ defined by Griffin-Levinson-Woo and give a Borel-style presentation for the equiโ€ฆ

Quantitative homogenization of the maximal action of curves in a Brownian potential

Felix Otto, Matteo Palmieri ยท 2026

Motivated by an optimal-matching problem (Leighton-Shor) and the random-field Ising model (Aizenman-Wehr, Ding-Wirth), we consider a variational problem for graphs in $1+1$ dimension maximizing an actโ€ฆ

k[x]-modules and Core-Nilpotent endomorphisms

Diego Alba Alonso, Javier Sanchez Gonzalez ยท 2026

Core-nilpotent endomorphisms over an arbitrary vector space form the largest subset of the ring of endomorphisms over that arbitrary vector space which admit a decomposition as sum of two endomorphismโ€ฆ

On a group ring identity related to the Alon-Jaeger-Tarsi conjecture

Janos Nagy, Peter Pal Pach ยท 2026

In this note we formulate a conjecture about two group ring identities and prove that it would imply the Alon-Jaeger-Tarsi conjecture.โ€ฆ

Metrics on triangulated categories and restrictions of (co)-$t$-structures

Wei Hu, Ziheng Liu ยท 2026

This paper explores the restriction behavior of silting-induced $t$-structures and co-$t$-structures on triangulated categories endowed with metrics. For compactly generated triangulated categories adโ€ฆ

Reachability-Based Design Optimization for Aircraft Maneuverability

Steven Nguyen, Nicholas Orndorff, Jorge Cortes, Boris Kramer ยท 2026

This paper presents a method for incorporating control analysis into design optimization for highly-maneuverable aircraft. By studying reachable sets for aircraft dynamics, we ensure that the optimizeโ€ฆ

Unitary representations and von Neumann's continuous geometries

Friedrich Martin Schneider, Andreas Thom ยท 2026

We prove that the unit group of a non-discrete irreducible, continuous ring, in the sense of John von Neumann, does not admit any non-trivial unitary representation continuous with respect to the stroโ€ฆ

On $S$-Noetherian Lattices

Sachin Sarode, Chetan Patil, Vinayak Joshi ยท 2026

In this paper, we define and study $S$-Noetherian lattices as a natural generalization of Noetherian rings. We prove that a ring $R$ is $S$-Noetherian if and only if its ideal lattice, $Id(R)$, is $S_โ€ฆ

Cut and paste invariants of moduli spaces of stable maps to toric surfaces

Cat Rust ยท 2026

We study moduli spaces of logarithmic stable maps to proper toric surfaces with prescribed tangency conditions to the toric boundary. Fixing a surface, we define a chamber decomposition on the space oโ€ฆ

The coordinate ring of the universal centralizer via Demazure operators

Tom Gannon, Victor Ginzburg ยท 2026

We give a simple description of the coordinate ring of the universal centralizer associated to a simply connected semisimple group. To this end, we prove a general result on Weil restriction of affineโ€ฆ

Exact Closed-Form Formulae for Linear and Circular Continuous Scan Statistics: $P_c(N - 1; N, w)$, $P_c(3; N, w)$, and $P(3; N, w)$

Haowei Yuan ยท 2026

The continuous linear $P(k; N, w)$ and circular scan statistics $P_c(k; N, w)$ are fundamental tools in probability and spatial statistics, frequently used to detect clustering in uniform data. Let $Xโ€ฆ
