Abstract:

For a number l >= 2, let G(l) denote the family of graphs which have girth 2l+1 and have no odd hole with length greater than 2l+1. Wu et al. conjectured that every graph in U(l >= 2)Gl is 3-colorable. Chudnovsky et al. and Wu et al., respectively, proved that every graph in G(2) and G(3) is 3-colorable. In this paper, we prove that every graph in U(l >= 5)Gl is 3-colorable.
