Sufficient conditions for the existence of path-factors with given properties

Hui Qin, Guowei Dai, Yuan Chen +2

A spanning subgraph $H$ of a graph $G$ is called a $P_{\geq k}$ -factor of $G$ if every component of $H$ is isomorphic to a path of order at least $k$ , where $k \geq 2$ is an integer.…

Component factors in $K_{1, r}$ -free graphs

Guowei Dai, Zan-Bo Zhang, Xiaoyan Zhang

A graph is said to be $K_{1, r}$ -free if it does not contain an induced subgraph isomorphic to $K_{1, r}$ . An $F$ -factor is a spanning subgraph $H$ such that each connected…
