Exponential odd-distance sets under the Manhattan metric
Alberto Espuny DÃaz, Emma Hogan, Freddie Illingworth +3
We construct a set of points in such that all pairwise Manhattan distances are odd integers, which improves the recent linear lower bound of Golovanov, Kupavsk…
Infinite Schnyder Woods
Louigi Addario-Berry, Emma Hogan, Lukas Michel +1
It is well-known that any finite triangulation possesses a unique maximal Schnyder wood. We introduce Schnyder woods of infinite triangulations, and prove there exists a unique max…
Sharp bounds for covering with large cliques and independent sets
Veronica Bitonti, Emma Hogan, Tommy Walker Mackay
Let be the least integer such that there exists a graph on vertices in which every vertex is contained in both a clique of size and an independent set o…
Tight Bounds for Hypercube Minor-Universality
Emma Hogan, Lukas Michel, Alex Scott +3
Benjamini, Kalifa and Tzalik recently proved that there is an absolute constant such that any graph with at most edges and no isolated vertices is a minor of th…
The excluded minors for the intersection of bicircular and lattice path matroids
Emma Hogan, Charles Semple
The classes of bicircular matroids and lattice path matroids are closed under minors. The complete list of excluded minors for the class of lattice path matroids is known, and it h…
Observations From an Online Security Competition and Its Implications on Crowdsourced Security
Alejandro Cuevas, Emma Hogan, Hanan Hibshi +1
The crowd sourced security industry, particularly bug bounty programs, has grown dramatically over the past years and has become the main source of software security reviews for ma…
