Order by disorder up to arbitrarily high temperature

Ravish Mehta ยท 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 haโ€ฆ

Structural description of (bull, house)-free graphs

Manoj Belavadi, Chinh T. Hoang ยท 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 butโ€ฆ

Property $R_\infty$ for generalized Higman groups

Ignat Soroko, Nicolas Vaskou ยท 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 gโ€ฆ

Separation profiles of free products

David Hume ยท 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 calโ€ฆ

A Note on Interdiction of Linear Minimization Problems

Yu Cong, Kangyi Tian ยท 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 faโ€ฆ

On the (algebraic) notion of 2-ring

Josep Elgueta ยท 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}, duโ€ฆ
