Counting faces of graphical zonotopes
Year: 2016
Type: preprint
Abstract: It is a classical fact that the number of vertices of the graphical zonotope $Z_Γ$ is equal to the number of acyclic orientations of a graph $Γ$. We show that the $f$-polynomial of $Z_Γ$ is obtained as the principal specialization of the $q$-analog of the chromatic symmetric function of $Γ$.
