图的关联着色是从关联集到颜色集的一个映射,使得关联集中任何两个相邻的关联都具有不同的像.确定了Meredith图的关联色数,证明了对任意系列平行图都存在一个(Δ+2,2)-关联着色.
An incidence coloring of graph is a coloring of its incidences in which neighboring incidences are assigned different colors.The incidence chromatic number of Meredith graph will be determined and a (Δ+2,2)-incidence coloring of any series-parallel graphs is given.
