Sufficient conditions for a special factor in a graph with minimum degree

Sizhong Zhou

Let $G$ be a graph. The size and the signless Laplacian spectral radius of $G$ are denoted by $e (G)$ and $q (G)$ , respectively. A spanning subgraph $F$ of $G$ is called an $H_{b}$ -fac…

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…

A result on fractional (a,b,k)-critical covered graphs

Sizhong Zhou, Quanru Pan

For a graph $G$ , the set of vertices in $G$ is denoted by $V (G)$ , and the set of edges in $G$ is denoted by $E (G)$ . A fractional $[a, b]$ -factor of a graph $G$ is a function $h$ fro…

Independence number and connectivity for fractional (a,b,k)-critical covered graphs

Sizhong Zhou, Jiancheng Wu, Hongxia Liu

A graph $G$ is a fractional $(a, b, k)$ -critical covered graph if $G - U$ is a fractional $[a, b]$ -covered graph for every $U \subseteq V (G)$ with $∣ U ∣ = k$ , which is first defined by Zhou…
