Line transversals in families of connected sets the plane

Daniel McGinnis, Shira Zerbib

We prove that if a family of compact connected sets in the plane has the property that every three members of it are intersected by a line, then there are three lines intersecting…

Rainbow paths and large rainbow matchings

Ron Aharoni, Eli Berger, Maria Chudnovsky +1

A conjecture of the first two authors is that matchings of size in any graph have a rainbow matching of size . We prove a lower bound of , improving on…

Large triangle packings and Tuza's conjecture in sparse random graphs

Patrick Bennett, Andrzej Dudek, Shira Zerbib

The triangle packing number of a graph is the maximum size of a set of edge-disjoint triangles in . Tuza conjectured that in any graph there exists a set of at mo…

The geometry and combinatorics of discrete line segment hypergraphs

Deborah Oliveros, Christopher O'Neill, Shira Zerbib

An -segment hypergraph is a hypergraph whose edges consist of consecutive integer points on line segments in . In this paper, we bound the chromatic number…

Envy-free cake division without assuming the players prefer nonempty pieces

Frédéric Meunier, Shira Zerbib

Consider players having preferences over the connected pieces of a cake, identified with the interval . A classical theorem, found independently by Stromquist and by Woo…
