A strict upper volume bound for minimal graphs in the unit ball

Qing Cui

Let $u$ be a solution of the minimal surface equation on a domain containing the closed unit ball $B^{n} \subset R^{n}$ . A classical calibration argument gives $|Graph…

Some results on minimum saturated graphs

Chenke Zhang, Qing Cui, Jinze Hu +2

Let $G$ be a graph and $F$ be a family of graphs. We say a graph $G$ is $F$ -saturated if $G$ does not contain any member in $F$ and for any $e\in E(\o…

The saturation number of W 4

Ning Song, Jinze Hu, Shengjin Ji +1

For a fixed graph $H$ , a graph $G$ is called $H$ -saturated if $G$ does not contain $H$ as a (not necessarily induced) subgraph, but $G + e$ contains a copy of $H$ for any $e\in E(\ov…
