On zero-sum polytopes: reciprocity, rigidity, and cyclic sieving

Dongchun Han, Xuan Wang, Hanbin Zhang +1

Let $G$ be a finite abelian group of order $n$ , and let $M (G, m)$ denote the set of zero-sum sequences over $G$ of length $m$ . We introduce the zero-sum polytope $\mathcal P…

On immanants of Cayley tables

Xuan Wang, Hanbin Zhang

Let $G$ be a finite abelian group of order $n$ and let $M_{G} = (x_{a + b})_{a, b \in G}$ be the Cayley table of $G$ . Let $imm_{I^} » (M_{G})$ be the immanant of $\mathca…
