A tight lower bound on the minimal dispersion

M Trödler, J Volec, J Vybíral - European Journal of Combinatorics, 2024 - Elsevier
We give a new lower bound for the minimal dispersion of a point set in the unit cube and its
inverse function in the high dimension regime. This is done by considering only a very small …

Minimal dispersion of large volume boxes in the cube

KS MacKay - Journal of Complexity, 2022 - Elsevier
In this note we present a construction which improves the best known bound on the minimal
dispersion of large volume boxes in the unit cube. Let d> 1. The dispersion of T⊂[0, 1] d is …

[HTML][HTML] Minimal dispersion on the cube and the torus

A Arman, AE Litvak - Journal of Complexity, 2024 - Elsevier
We improve some upper bounds for minimal dispersion on the cube and torus. Our new
ingredient is an improvement of a probabilistic lemma used to obtain upper bounds for …

A New Construction of Forests with Low Visibility

K Kashkan - arXiv preprint arXiv:2407.01633, 2024 - arxiv.org
A set of points with finite density is constructed in $\mathbb {R}^ d $, with $ d\geq2 $, by
adding points to a Poisson process such that any line segment of length $ O\left …

The minimal spherical dispersion

J Prochno, D Rudolf - The Journal of Geometric Analysis, 2024 - Springer
We prove upper and lower bounds on the minimal spherical dispersion, improving upon
previous estimates obtained by Rote and Tichy in (Anz Österreich Akad Wiss Math Nat Kl …
