Universal sequences of lines in $R^{d}$

Imre Bárány, Gil Kalai, Attila Pór

One of the most important and useful examples in discrete geometry is a finite sequence of points on the moment curve $γ (t) = (t, t^{2}, t^{3}, \dots, t^{d})$ or, more generally, on a {\it st…

Random bipartite posets and extremal problems

Csaba Biró, Peter Hamburger, H. A. Kierstead +3

Previously, Erdős, Kierstead and Trotter investigated the dimension of random height~ $2$ partially ordered sets. Their research was motivated primarily by two goals: (1)~analyzing…

Almost-equidistant sets

Martin Balko, Attila Pór, Manfred Scheucher +2

For a positive integer $d$ , a set of points in $d$ -dimensional Euclidean space is called almost-equidistant if for any three points from the set, some two are at unit distance. Let…

Double Threshold Digraphs

Peter Hamburger, Ross M. McConnell, Attila Pór +1

A semiorder is a model of preference relations where each element $x$ is associated with a utility value $α (x)$ , and there is a threshold $t$ such that $y$ is preferred to $x$ iff…

Blocking Coloured Point Sets

Greg Aloupis, Brad Ballinger, Sébastien Collette +3

This paper studies problems related to visibility among points in the plane. A point $x$ \emph{blocks} two points $v$ and $w$ if $x$ is in the interior of the line segment $\bar{vw…
