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 Mihail-Vazirani conjecture and strong edge-expansion in random $0/1$ polytopes

Micha Christoph, Sahar Diskin, Lyuben Lichev, Benny Sudakov · 2026

We study the edge-expansion of the graph of a random $0/1$ polytope $P^d_p$, defined as the convex hull of a random subset of the points in $\{0,1\}^d$ where every point is retained independently and …

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 …

Phase transitions in Doi-Onsager, Noisy Transformer, and other multimodal models

Kyunghoo Mun, Matthew Rosenzweig · 2026

We study phase transitions for repulsive-attractive mean-field free energies on the circle. For a $\frac{1}{n+1}$-periodic interaction whose Fourier coefficients satisfy a certain decay condition, we …

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…

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…
