Polymatroids and moduli of points in flags
Patricio Gallardo, Javier González-Anaya, José Luis González
We introduce and study different compactifications of the moduli space of distinct weighted labeled points in a flag of affine spaces. We construct these spaces via the weighte…

Higher-dimensional Losev-Manin spaces and their geometry
Patricio Gallardo, Javier González-Anaya, José Luis González +1
The classical Losev-Manin space is a toric compactification of the moduli space of points in the affine line modulo translation and scaling. Motivated by this, we study its hig…

Non-existence of negative curves
Javier González-Anaya, José Luis González, Kalle Karu
Let be a projective toric surface of Picard number one blown up at a general point. We bring an infinite family of examples of such whose Kleiman-Mori cone of curves is not…
