Non-symmetrically $t$-affine functions revisited

Tibor Kiss, Dora Koroknai · 2026

In 2014, Michal Lewicki and Andrzej Olbry\'s proved that if a real valued function $f$ defined on the real line satisfies the conditional functional equation \[ f(tx + (1-t)y) = t f(x) + (1-t) f(y),\q…

The Steklov spectrum of convex polygonal domains II: investigating spectral determination

Emily B. Dryden, Carolyn Gordon, Javier Moreno, Julie Rowlett, Carlos Villegas-Blas · 2026

The extent to which the geometry of an object is determined by some associated spectral data is a longstanding problem. We investigate this problem in the context of the Steklov spectrum, focusing on …

Surreal Arithmetic, Lazily

Lloyd Allison · 2026

Conway's surreal numbers were aptly named by Knuth. This note examines how far one can get towards implementing surreals and the arithmetic operations on them so that they execute efficiently. Lazy ev…

Mathematical modeling of biochemical signal propagation in many-stage enzymatic pathways

Chathranee Jayathilaka, Mark B. Flegg · 2026

Biochemical signalling cascades transduce extracellular stimuli into cellular responses through sequences of discrete, node-to-node activations. While signal fidelity depends critically on local inter…

A quadratic form generalization of rational dinv

Yifeng Huang · 2026

We introduce a quadratic form $Q$ on the space of functions on the gap poset $G$ of the numerical semigroup $\langle a,b\rangle$. We prove combinatorially that when evaluated on the indicator function…

Random 0/1-polytopes expand rapidly

He Guo, Istvan Tomon · 2026

A 0/1-polytope is the convex hull of a subset $V\subseteq \{0,1\}^n$. A celebrated conjecture of Mihail and Vazirani asserts that the graph of every 0/1-polytope has edge-expansion at least 1. In this…

Sharp threshold for reconstructing points on the line

Georgii Zakharov · 2026

For a set of $n$ points $V \subseteq \mathbb{R}$ let $G(V, p)$ be the random graph on $V$ where each possible edge is present independently with probability $p$. We call a subset $U \subseteq V$ {\emp…

On the Structure of Asymptotic Space of the Lobachevsky Plane

Alexander Shnirelman · 2026

The notion of asymptotic space for an unbounded metric space has been introduced by Micha Gromov in 1980s. It is intended to capture the structure of a metric space at infinity. The most comprehensive…

Makkai's lost proof of projectivity of N in the free topos

Henrik Forssell, Peter LeFanu Lumsdaine, Andrew W. Swan · 2026

We give a categorical proof of the projectivity of $N$ in the free topos -- in proof-theoretic terms, the rule of countable choice for intuitionistic higher-order logic -- based on the unpublished pro…
