Affine quermassintegrals of random polytopes

Giorgos Chasapis, Nikos Skarmogiannis

A question related to some conjectures of Lutwak about the affine quermassintegrals of a convex body $K$ in $R^{n}$ asks whether for every convex body $K$ in ${\mathbb R}^n…

Norms of weighted sums of log-concave random vectors

Giorgos Chasapis, Apostolos Giannopoulos, Nikos Skarmogiannis

Let $C$ and $K$ be centrally symmetric convex bodies of volume $1$ in $R^{n}$ . We provide upper bounds for the multi-integral expression \begin{equation*}\|{\bf t}\|_{C^s,K…

A note on norms of signed sums of vectors

Giorgos Chasapis, Nikos Skarmogiannis

Our starting point is an improved version of a result of D. Hajela related to a question of Komlós: we show that if $f (n)$ is a function such that $\lim\limits_{n\to\infty }f(n)=\i…

Threshold phenomena for high-dimensional random polytopes

Gilles Bonnet, Giorgos Chasapis, Julian Grote +2

Let $X_{1}, \dots, X_{N}$ , $N > n$ , be independent random points in $R^{n}$ , distributed according to the so-called beta or beta-prime distribution, respectively. We establish thre…
