Random polytopes in convex bodies: Bridging the gap between extremal containers

F Besau, A Gusakova, C Thäle - arxiv preprint arxiv:2411.19163, 2024 - arxiv.org
We investigate the asymptotic properties of random polytopes arising as convex hulls of $ n
$ independent random points sampled from a family of block-beta distributions. Notably, this …

Intrinsic and dual volume deviations of convex bodies and polytopes

F Besau, S Hoehner, G Kur - … Mathematics Research Notices, 2021 - academic.oup.com
We establish estimates for the asymptotic best approximation of the Euclidean unit ball by
polytopes under a notion of distance induced by the intrinsic volumes. We also introduce a …

An intrinsic volume metric on the class of convex bodies

F Besau - 2023 - dmg.tuwien.ac.at
In this talk I will present on a recent joint work with S. Hoehner, where we introduce a new
intrinsic volume metric for the class of convex bodies in Rn. As an application we prove an …

A new intrinsic volume metric is introduced for the class of convex bodies in ℝ n. As an
application, an inequality is proved for the asymptotic best approximation of the Euclidean …

On the Optimality of Random Partial Sphere Coverings in High Dimensions

S Hoehner, G Kur - arxiv preprint arxiv:2501.10607, 2025 - arxiv.org
Given $ N $ geodesic caps on the normalized unit sphere in $\mathbb {R}^ d $, and whose
total surface area sums to one, what is the maximal surface area their union can cover? We …

[PDF][PDF] THE EXPECTED Lp SURFACE AREA OF A RANDOM POLYTOPE INSCRIBED IN A BALL

For p∈[0, 1], an asymptotic formula is proved for the expected Lp surface area of the random
convex hull of a fixed number of points sampled uniformly and independently from the …
