摘要
研究了若干广义Petersen图G(n,r)的邻点可区别全染色。构造性地证明了:若n≡0(mod 4),r■0(mod 4)或n≡0(mod 5),r■0(mod 5),则G(n,r)的邻点可区别全色数为5。
The adjacent vertex-distinguishing total coloring of some generalized Peterson graphs G( n, r) were studied. It was constructively proved that if n=0(mod 4), r≠0(mod 4) or n=0(mod 5), r≠0(mod 5), then the adjacent vertex-distinguishing total chromatic number of G( n, r) is five.
