Polytopes with large transversal ratio

Michael Gene Dobbins, Seunghun Lee

The transversal ratio of a polytope $P$ is the minimum proportion of vertices of $P$ required to intersect each facet of $P$ . The weak chromatic number of $P$ is the minimum number…

On colorings of hypergraphs embeddable in $R^{d}$

Seunghun Lee, Eran Nevo

The (weak) chromatic number of a hypergraph $H$ , denoted by $I ¨ (H)$ , is the smallest number of colors required to color the vertices of $H$ so that no hyperedge of $H$ is monochrom…
