Further Consequences of the Colorful Helly Hypothesis

Leonardo Martínez-Sandoval, Edgardo Roldán-Pensado, Natan Rubin

Let $F$ be a family of convex sets in $R^{d}$ , which are colored with $d + 1$ colors. We say that $F$ satisfies the Colorful Helly Property if every rainb…

On a Helly-type question for central symmetry

Alexey Garber, Edgardo Roldán-Pensado

We study a certain Helly-type question by Konrad Swanepoel. Assume that $X$ is a set of points such that every $k$ -subset of $X$ is in centrally symmetric convex position, is it tr…
