Abstract:We define the codegree of a given graph as the maximum number of neighbors that any two distinct vertices have in common.

In 2002, V. Vu proposed that for a given graph, its chromatic number should never be too much larger than its codegree, provided that its codegree is not too small as a proportion of its maximum degree.
