Enumeration of spanning trees and resistance distances of generalized blow-up graphs

Hechao Liu, Lu Li, Lihua You +2

Let $H$ be a graph with vertex set $V (H) = {v_{1}, v_{2}, \dots, v_{k}}$ . The generalized blow-up graph $H_{p_{1}, \dots, p_{k}}^{q_{1}, \dots, q_{k}}$ is constructed by replacing each vertex $v_…

On determinants of tournaments and $D_{k}$

Jing Zeng, Lihua You

Let $T$ be a tournament with $n$ vertices $v_{1}, \dots, v_{n}$ . The skew-adjacency matrix of $T$ is the $n \times n$ zero-diagonal matrix $S_{T} = [s_{ij}]$ in which $s_{ij} = - s_{j i} = 1$ if…
