On toric ideals arising from signed graphs

JiSun Huh, Sangwook Kim, Boram Park

A signed graph is a pair $(G, τ)$ of a graph $G$ and its sign $τ$ , where a \textit{sign} $τ$ is a function from ${(e, v) ∣ e \in E (G), v \in V (G), v \in e}$ to ${1, - 1}$ . Note that…

Refined enumeration of vertices among all rooted ordered $d$ -trees

Sangwook Kim, Seunghyun Seo, Heesung Shin

In this paper we enumerate the cardinalities for the set of all vertices of outdegree $\geq k$ at level $\geq ℓ$ among all rooted ordered $d$ -trees with $n$ edges. Our results uni…
