A variant of Schur's product theorem and its applications

Jan Vybíral

We show the following version of the Schur's product theorem. If $M = (M_{j, k})_{j, k = 1}^{n} \in R^{n \times n}$ is a positive semidefinite matrix with all entries on the diagona…

On the volume of unit balls of finite-dimensional Lorentz spaces

Anna Doležalová, Jan Vybíral

We study the volume of unit balls $B_{p, q}^{n}$ of finite-dimensional Lorentz sequence spaces $ℓ_{p, q}^{n} .$ We give an iterative formula for $vol (B_{p, q}^{n})$ for the weak Leb…

Deterministic constructions of high-dimensional sets with small dispersion

Mario Ullrich, Jan Vybíral

The dispersion of a point set $P \subset [0, 1]^{d}$ is the volume of the largest box with sides parallel to the coordinate axes, which does not intersect $P$ . Here, we show a construct…
