Signless Laplacian spectral conditions for even factors in graphs

Lu Li, Hechao Liu, Hongbo Hua +1

A spanning subgraph $F$ of a graph $G$ is defined as an even factor of $G$ , if the degree $d_{F} (v) = 2 k, k \in N^{+}$ for every vertex $v \in V (G)$ . This note establishes a suffic…

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_…
