摘要
研究了当G为n阶轮,或扇,或星时,字典积图G[H]的Mycielski图M(G[H])的点可区别全染色,其中n≥6且H为m阶简单图.得到了以下结果:①若H为m阶完全图,则M(G[H])的点可区别全色数为2mn;②若H为m阶路,其中m≥4,则M(G[H])的点可区别全色数为2(n-1)m+6.
We study the vertex- distinguishing total colorings of the Mycielski' s graph M( G[H] ) of the lexicographic product graph G[H], where G is a wheel, or fan, or star with n vertices, n≥6, and H is a simple graph with m vertices. And we give the following results:① If H is a complete graph with m vertices, then the vertex - distinguishing total chromatic number of M( G[H] ) is 2ran ; ② If H is a path with m vertices, where m ≥ 4, then the vertex - distinguishing total chromatic number of M is 2(n-1)m +6.
