摘要
本文研究广义Petersen图GP(n,k)的点着色、边着色和点-边全着色,得到广义Petersen图GP(n,2)的点色数、边色数和全色数,同时还得到当n为偶数,k为奇数时,该广义Petersen图GP(n,k)满足点-边全着色猜想等结论.
The vertex colouring,edge colouring and vertex-edge total colouring of extended Petersen graph GP(n,k) are studied in the paper.We obtained the vertex chromatic number and edge chromatic number of the extended Petersen graph GP(n,k),and then the total colouring conjecture is ture at the extended Petersen graph GP(n,k),as n is even and k is odd,etc.
