英文摘要 | The minimum number of colors needed to properly color the vertices and edges of a graph G is called the total chromatic number of G and denoted by chi ''(G). It is shown that if a planar graph G has maximum degree Delta >= 9, then chi ''(G) = Delta + 1. In this paper, we prove that if G is a planar graph with maximum degree 8 and without intersecting chordal 4-cycles, then chi ''(G) = 9. |
