Order by disorder up to arbitrarily high temperature

Ravish Mehta · 2026

We prove that a class of classical lattice models on $\mathbb{Z}^d$ ($d \geq 2$) with on-site space $\mathbb{N}_0$ exhibits long-range checkerboard order at sufficiently high temperature. The model ha…

Structural description of (bull, house)-free graphs

Manoj Belavadi, Chinh T. Hoang · 2026

The bull is a graph consisting of a triangle and two pendant edges. The P_5 is the chordless path on five vertices. The house is the complement of a P_5. A graph is k-critical if it is k-chromatic but…

Property $R_\infty$ for generalized Higman groups

Ignat Soroko, Nicolas Vaskou · 2026

We give a unified proof of property $R_\infty$ for the Higman groups $H_n$ ($n\ge 4$) and for their generalizations studied by Martin and Horbez--Huang. As a key step, we prove that the automorphism g…

Families of Unit Equations and Exponential Diophantine Problems via Integral Points

Julie Tzu-Yueh Wang, Zheng Xiao · 2026

This paper investigates the distribution of integral points on projective varieties via two distinct methods: the Ru-Vojta theorem and our higher-dimensional generalization of the Huang-Levin-Xiao ine…

Separation profiles of free products

David Hume · 2026

We deduce from a theorem of Dvorak--Norin that the separation and treewidth profiles of graphs are asymptotically equivalent, resolving a question of Huang--Hume--Kelly--Lam. As an application, we cal…

On the Cauchy problem for the multi-dimensional compressible Navier-Stokes-Korteweg system: Global strong solutions with arbitrarily large initial data

Xiangdi Huang, Muxi Lei, Huitao Zhou · 2026

Since the pioneering work of Korteweg (1901) and the subsequent refinement of capillary fluid models by Dunn and Serrin (1985), the global existence of strong solutions to the multi-dimensional compre…

A Note on Interdiction of Linear Minimization Problems

Yu Cong, Kangyi Tian · 2026

Motivated by the FPTAS for connectivity interdiction of Huang et al. (IPCO'24), we isolate the part of the argument that does not use cuts. The setting is a minimization problem over a feasible-set fa…

Scissors modes in generalized Gross-Pitaevskii equations

Neelam Shukla, Oleksandr V. Marchukov, Bastien Humbert, Jan Arlt, Jeremy Armstrong, Artem G. Volosniev · 2026

We investigate scissors modes in nonlinear systems with arbitrary power-law dependence of the nonlinear term. Through analytical derivation, we establish a general expression demonstrating that, in th…

On non-relativistic integrable models and 4d SCFTs

Rotem Ben Zeev, Anirudh Deb, Hee-Cheol Kim, Shlomo S. Razamat · 2026

We elaborate on the relation between the generalized Schur index of $N=2$ SCFTs in four dimensions and the non-relativistic limit of the elliptic Ruijsenaars-Schneider model. In particular we discuss …

Chevalley property of module-finite Hopf algebras and discriminant ideals

Yimin Huang, Tiancheng Qi, Quanshui Wu, Ruipeng Zhu · 2026

In this paper, we study the Chevalley property of Cayley-Hamilton Hopf algebras in the sense of De Concini-Procesi-Reshetikhin-Rosso using discriminant ideals. For any affine Cayley-Hamilton Hopf alge…

The Huang Algebra Ideal and the Diagonal Shift Property

Darlayne Addabbo · 2026

Let $V$ be a grading-restricted vertex algebra and let $A^\infty(V)=U^\infty(V)/Q^\infty(V)$ be the associative algebra constructed by Huang, where $U^\infty(V)$ is the space of column-finite infinite…

Faster Approximate Linear Matroid Intersection

Tatsuya Terao · 2026

We consider a fast approximation algorithm for the linear matroid intersection problem. In this problem, we are given two $r \times n$ matrices $M_1$ and $M_2$, and the objective is to find a largest …

On the (algebraic) notion of 2-ring

Josep Elgueta · 2026

By a 2-ring we mean a groupoid with a structure analogous to that of a ring, up to coherent isomorphisms. Two different notions of 2-ring appear in the literature: the notion of {\em Ann-category}, du…

Edge universality in Floquet sideband spectra

Miguel Tierz · 2026

We show that, for non-interacting fermions under a monochromatic phase drive (Tien--Gordon regime), the outgoing sideband occupations at a sharp Fermi edge are governed by the discrete Bessel kernel -…
