The average distance of spanning trees in terms of independence number

Zhibin Du, Xuli Qi

Let $G$ be a connected graph with vertex set $V (G)$ , and denote by $d_{G} (u, v)$ the distance from $u$ to $v$ in $G$ , for any $u, v \in V (G)$ . The average distance of an $n$ -vertex con…

Determinants of Steiner Distance Hypermatrices

Joshua Cooper, Zhibin Du

Generalizing work from the 1970s on the determinants of distance hypermatrices of trees, we consider the hyperdeterminants of order- $k$ Steiner distance hypermatrices of trees on $…
