Some exact values on Ramsey numbers related to fans

Qinghong Zhao, Bing Wei

For two given graphs $F$ and $H$ , the Ramsey number $R (F, H)$ is the smallest integer $N$ such that any red-blue edge-coloring of the complete graph $K_{N}$ contains a red $F$ or a bl…

a characterization of the centers of chordal graphs

James M Shook, Bing Wei

A graph is $k$ -chordal if it does not have an induced cycle with length greater than $k$ . We call a graph chordal if it is $3$ -chordal. Let $G$ be a graph. The distance between the…

Bonds intersecting long paths in $k$ -connected graphs

Bing Wei, Haidong Wu, Qinghong Zhao

A well-known question of Gallai (1966) asked whether there is a vertex which passes through all longest paths of a connected graph. Although this has been verified for some special…
