摘要
本文得到了有关乘积图的全色数的一些结果,并利用这些结果证明了Mesh图和Tours-图均满足全色数猜想.特别,几乎所有的Mesh-图都是第一类图.
New results about the total chromatic numbers of product graphs are presened. With our new results,it is proved that both Mesh-graphs and Torus-graphs satisfy the total chromatic number conjecture. Particularly, it is proved that except K, and K2×K2, all of the other Mesh-graphs are in the first class.
