Using Block Designs in Crossing Number Bounds

John Asplund, Eva Czabarka, Gregory Clark +6

The crossing number ${\mbox {cr}}(G)$ of a graph is the smallest number of edge crossings over all drawings of in the plane. For any , the -planar crossing…

New Perspectives on Neighborhood-Prime Labelings of Graphs

John Asplund, N. Bradley Fox, Arran Hamm

Neighborhood-prime labeling is a variation of prime labeling. A labeling is a neighborhood-prime labeling if for each vertex with degree greater t…

The k-planar crossing number of random graphs and random regular graphs

John Asplund, Thao Do, Arran Hamm +3

We give an explicit extension of Spencer's result on the biplanar crossing number of the Erdos-Renyi random graph . In particular, we show that the k-planar crossing number…

On Erdős-Ko-Rado for random hypergraphs I

Arran Hamm, Jeff Kahn

A family of sets is intersecting if no two of its members are disjoint, and has the Erdős-Ko-Rado property (or is EKR) if each of its largest intersecting subfamilies has nonempty…

On Erdős-Ko-Rado for random hypergraphs II

Arran Hamm, Jeff Kahn

Denote by the random -graph in which each -subset of is present with probability , independent of other choices. More or less answering…
