Jim Geelen, Florian Hoersch
We relate two conjectures that play a central role in the reported proof of Rota's Conjecture. Let be a finite field. The first conjecture states that: the branch-width…

On the complex-representable excluded minors for real-representability
Rutger Campbell, Jim Geelen
We show that each real-representable matroid is a minor of a complex-representable excluded minor for real-representability. More generally, for an infinite field an…
