Sparse metric hypergraphs

Vašek Chvátal, Guillermo A. Gamboa Quintero., Ida Kantor

Given a metric space $(X, ρ)$ , we say $y$ is between $x$ and $z$ if $ρ (x, z) = ρ (x, y) + ρ (y, z)$ . A metric space gives rise to a 3-uniform hypergraph that has as hyperedges those tri…

Metric hypergraphs and metric-line equivalences

Vašek Chvátal, Ida Kantor

In a metric space $M = (X, d)$ , we say that $v$ is between $u$ and $w$ if $d (u, w) = d (u, v) + d (v, w)$ . Taking all triples ${u, v, w}$ such that $v$ is between $u$ and $w$ , one can associat…

Patterns of conjunctive forks

Vašek Chvátal, František Matúš, Yori Zwólš

Three events in a probability space form a conjunctive fork if they satisfy specific constraints on conditional independence and covariances. Patterns of conjunctive forks within c…
