Singular matroid realization spaces
Daniel Corey, Dante Luber
We study smoothness of realization spaces of matroids for small rank and ground set. For -realizable matroids, when the rank is , we prove that the realization space…

The Grassmannian of 3-planes in is schön
Daniel Corey, Dante Luber
We prove that the open subvariety of the Grassmannian determined by the nonvanishing of all Plücker coordinates is schön, i.e.,…

Boundary complexes of moduli spaces of curves in higher genus
Emily Clader, Dante Luber, Kyla Quillin
Given a collection of boundary divisors in the moduli space of stable genus-zero n-pointed curves, Giansiracusa proved that their intersection is nonempty if and only if all pairwi…
