$q$ -Chromatic polynomials

Esme Bajo, Matthias Beck, AndrÃ©s R. Vindas-MelÃ©ndez

We study a $q$ -version of the chromatic polynomial of a given graph $G = (V, E)$ , namely, \[ Ï_G^Î»(q,n) \ := \sum_{\substack{\text{proper colorings}\\ c\,:\,V\to[n]}} q^{ \sum_{ v \…

Local $h^{*}$ -polynomials for one-row Hermite normal form simplices

Esme Bajo, Benjamin Braun, Giulia Codenotti +2

The local $h^{*}$ -polynomial of a lattice polytope is an important invariant arising in Ehrhart theory. Our focus is on lattice simplices presented in Hermite normal form with a sing…
