证明了每个立方Halin图H是完备6可着色的,并且H有一个完备6-着色,使得每一种色出现在每一个面(顶点)以及与其相邻(关联)的顶点、边和面的着色集中。
Every cubic Halin graph H has its complete chromatic number χc(H)=6.Furthermore,H admits a complete coloring λ such that for each w∈V(H)∪F(H) we have |{λ(x):x∈N(w)∪{w}}|=6,where F(H) is the face set,and N(w) is the set of faces,vertices and edges adjacent or incident with w in H.
