Spectral radii and star-factors with large components

Zhiren Sun, Sizhong Zhou

Let $G$ be a connected graph with $n$ vertices. The isolated toughness of $G$ , denoted by $I (G)$ , is defined by $I(G)=\min\left\{\frac{|S|}{i(G-S)}:S\subseteq V(G) \ \mbox{and} \ i…

Some sufficient conditions for path-factor uniform graphs

Sizhong Zhou, Zhiren Sun, Hongxia Liu

For a set $H$ of connected graphs, a spanning subgraph $H$ of $G$ is called an $H$ -factor of $G$ if each component of $H$ is isomorphic to an element of $\mathc…
