The existence of even factors based on spectral conditions of graphs

Jiasheng Li, Xiaoyun Lv, Shoujun Xu

Let $G = (V (G), E (G))$ be a graph with vertex set $V (G)$ and edge set $E (G)$ . An even factor of $G$ is a spanning subgraph $F$ such that every vertex in $F$ has a nonzero even degree…

On the minimum constant resistance curvature conjecture of graphs

Wensheng Sun, Yujun Yang, Shou-Jun Xu

Let $G$ be a connected graph with $n$ vertices. The resistance distance $I^c ◯_{G} (i, j)$ between any two vertices $i$ and $j$ of $G$ is defined as the effective resistance between the…
