Bounds for the rainbow disconnection number of graphs

Xuqing Bai, Zhong Huang, Xueliang Li

An edge-cut $R$ of an edge-colored connected graph is called a rainbow-cut if no two edges in the edge-cut are colored the same. An edge-colored graph is rainbow disconnected if fo…

The rainbow vertex-disconnection in graphs

Xuqing Bai, You Chen, Ping Li +2

Let $G$ be a nontrivial connected and vertex-colored graph. A subset $X$ of the vertex set of $G$ is called rainbow if any two vertices in $X$ have distinct colors. The graph $G$ i…

Extremality of graph entropy based on degrees of uniform hypergraphs with few edges

Dan Hu, Xueliang Li, Xiaogang Liu +1

Let $H$ be a hypergraph with $n$ vertices. Suppose that $d_{1}, d_{2}, \dots, d_{n}$ are degrees of the vertices of $H$ . The $t$ -th graph entropy based on degrees of $\…
