Radius, Girth and Minimum Degree

Vojtěch Dvořák, Peter van Hintum, Amy Shaw +1

Given a connected graph $G$ on $n$ vertices, with minimum degree $δ \geq 2$ and girth at least $g \geq 4$ , what is the maximum radius $r$ this graph can have? Erdős, Pach, Pollack a…

Sharp L1 Inequalities for Sup-Convolution

Peter van Hintum, Hunter Spink, Marius Tiba

Given a compact convex domain $C \subset R^{k}$ and bounded measurable functions $f_{1}, \dots, f_{n} : C \to R$ , define the sup-convolution $(f_{1} * \dots * f_{n}) (z)$ t…

Improved Bound for Tomaszewski's Problem

Vojtěch Dvořák, Peter van Hintum, Marius Tiba

In 1986, Tomaszewski made the following conjecture. Given $n$ real numbers $a_{1}, ..., a_{n}$ with $\sum_{i = 1}^{n} a_{i}^{2} = 1$ , then of the $2^{n}$ signed sums $\pm a_{1} \pm ... \p…
