Some exact values on Ramsey numbers related to fans

Qinghong Zhao, Bing Wei

For two given graphs and , the Ramsey number is the smallest integer such that any red-blue edge-coloring of the complete graph contains a red or a bl…

a characterization of the centers of chordal graphs

James M Shook, Bing Wei

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

Bonds intersecting long paths in -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…

A note on Gallai-Ramsey number of even wheels

Zi-Xia Song, Bing Wei, Fangfang Zhang +1

A Gallai coloring of a complete graph is an edge-coloring such that no triangle has all its edges colored differently. A Gallai -coloring is a Gallai coloring that uses colo…
