Idealness of $k$ -wise intersecting families

Ahmad Abdi, Gérard Cornuéjols, Tony Huynh +1

A clutter is \emph{ $k$ -wise intersecting} if every $k$ members have a common element, yet no element belongs to all members. We conjecture that, for some integer $k \geq 4$ , every $…

Clean tangled clutters, simplices, and projective geometries

Ahmad Abdi, Gérard Cornuéjols, Matt Superdock

A clutter is \emph{clean} if it has no delta or the blocker of an extended odd hole minor, and it is \emph{tangled} if its covering number is two and every element appears in a min…
