设G,H为简单图.给出直积图G×H的邻点可区别全色数的一个上界,得到星、轮、扇分别与m阶路、圈的直积图的邻点可区别全色数.
Let G, and H be simple graphs. Then, an upper bound of adjacent vertex distinguishing total coloring number on Cartesian product graphs GX H was given, so that adjacent vertex distinguishing total coloring number on Cartesian product G×Pm and G×Cm, where G was a star, fan or wheel.
