The moduli space of quasistable spin curves
Alex Abreu, Marco Pacini, Danny Taboada
We study a compactification of the moduli space of theta characteristics, giving a modular interpretation of the geometric points and describing the boundary stratification. This s…
Abel Maps for nodal curves via tropical geometry
Alex Abreu, Sally Andria, Marco Pacini
We consider Abel maps for regular smoothing of nodal curves with values in the Esteves compactified Jacobian. In general, these maps are just rational, and an interesting question…
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…
A symmetric function of increasing forests
Alex Abreu, Antonio Nigro
For an indifference graph we define a symmetric function of increasing spanning forests of . We prove that this symmetric function satisfies certain linear relations, which…
