A general formula for walk determinants of rooted products with applications to DGS-graph constructions

Wei Wang, Jie Shen, Lihuan Mao

For an $n$ -vertex graph $G$ , and a rooted graph $H^{(v)}$ with $v$ as the root, the rooted product graph $G \circ H^{(v)}$ is obtained from $G$ and $n$ copies of $H$ by identifying…

On the determinant of the walk matrix of the rooted product with a path

Zhidan Yan, Wei Wang

For an $n$ -vertex graph $G$ , the walk matrix of $G$ , denoted by $W (G)$ , is the matrix $[e, A (G) e, \dots, (A (G))^{n - 1} e]$ , where $A (G)$ is the adjacency matrix of $G$ and $e$ is the a…
