Proof of a conjecture on the determinant of walk matrix of rooted product with a path

Wei Wang, Zhidan Yan, Lihuan Mao

The walk matrix of an $n$ -vertex graph $G$ with adjacency matrix $A$ , denoted by $W (G)$ , is $[e, A e, \dots, A^{n - 1} e]$ , where $e$ is the all-ones vector. Let $G \circ P_{m}$ be the root…

The list-coloring function of signed graphs

Sumin Huang, Jianguo Qian, Wei Wang

It is known that, for any $k$ -list assignment $L$ of a graph $G$ , the number of $L$ -list colorings of $G$ is at least the number of the proper $k$ -colorings of $G$ when $k>(m-1)/\l…
