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…
