The minimum degree of minimal $k$ -factor-critical claw-free graphs*

Jing Guo, Qiuli Li, Fuliang Lu +1

A graph $G$ of order $n$ is said to be $k$ -factor-critical for integers $1 \leq k < n$ , if the removal of any $k$ vertices results in a graph with a perfect matching. A $k$ -factor-cr…

Cubic vertices of minimal bicritical graphs

Jing Guo, Hailun Wu, Heping Zhang

A graph $G$ with four or more vertices is called bicritical if the removal of any pair of distinct vertices of $G$ results in a graph with a perfect matching. A bicritical graph is…
