The Total Chromatic Number and Properties of Similar Outer Planar Graphs
Bao Quan-ao · Journal of Ningbo Institute of Education · 2005
In this paper,we study the construction properties of the Planar Graph G with only one internal vertex,so called similar Outer Planar Graph which gets the total edge-face chromatic number x_(ef)(G)≤6=△(G) △(G)≤5△(G)5,proving the total edge-face chromatic number;conjecture of the Planar Graphs.
