Chromatic symmetric functions from the modular law
Alex Abreu, Antonio Nigro
In this article we show how to compute the chromatic quasisymmetric function of indifference graphs from the modular law introduced by Guay-Paquet. We provide an algorithm which wo…

Minuscule Schubert calculus and the geometric Satake correspondence
Dave Anderson, Antonio Nigro
We describe a relationship between work of Laksov, Gatto, and their collaborators on realizations of (generalized) Schubert calculus of Grassmannians, and the geometric Satake corr…

Level- limit linear series
Eduardo Esteves, Antonio Nigro, Pedro Rizzo
We introduce the notion of level- limit linear series, which describe limits of linear series along families of smooth curves degenerating to a singular curve . We treat here…
