Spectral radius and k-factor-critical graphs

Sizhong Zhou, Zhiren Sun, Yuli Zhang

For a nonnegative integer $k$ , a graph $G$ is said to be $k$ -factor-critical if $G - Q$ admits a perfect matching for any $Q \subseteq V (G)$ with $∣ Q ∣ = k$ . In this article, we prove sp…

Signless Laplacian spectral radius for a k-extendable graph

Sizhong Zhou, Yuli Zhang

Let $k$ and $n$ be two nonnegative integers with $n \equiv 0$ (mod 2), and let $G$ be a graph of order $n$ with a 1-factor. Then $G$ is said to be $k$ -extendable for $0\leq k\leq\fra…
