Non-symmetrically $t$-affine functions revisited

Tibor Kiss, Dora Koroknai ยท 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),\qโ€ฆ

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

Emily B. Dryden, Carolyn Gordon, Javier Moreno, Julie Rowlett, Carlos Villegas-Blas ยท 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 โ€ฆ

Random 0/1-polytopes expand rapidly

He Guo, Istvan Tomon ยท 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 thisโ€ฆ

Sharp threshold for reconstructing points on the line

Georgii Zakharov ยท 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 $U \subseteq V$ {\empโ€ฆ

Identities and transformations for Lambert series and double Lambert series

Su-Ping Cui, Dazhao Tang ยท 2026

We establish two identities for Lambert series and double Lambert series, thereby resolving conjectures of Andrews, Dixit, Schultz and Yee (Acta Arith.~181:253--286, 2017), as well as Amdeberhan, Andrโ€ฆ
