摘    要:设G(V,E)是阶数至少为2的简单连通图,k是正整数,V∪E到{1,2,3,…,k)的映射f满足:对任意uυ,υw∈E(G),u≠w,有f(uv)≠f(υw);对任意uυ∈E(G),有,(u)≠,(υ),f(u)≠f(uυ),f(υ)≠f(uυ);那么称f为G的k-正常全染色,若,还满足对任意uυ∈E(G),有C(u)≠C(υ),其中C(u)={(u))∪{f(uυ)|uυ∈E(G),υ∈V(G)),那么称,为G的k-邻点可区别的全染色(简记为k-AVDTC),称min{k|G有k-邻点可区别的全染色)为G的邻点可区别的全色数,记作xat(G).本文得到了圈Cm和完全图Kn的笛卡尔积图Cm×Kn邻点可区别的全色数.

关 键 词:  全染色  邻点可区别全染色  邻点可区别全色数

Abstract:Let G be a simple graph. A k- proper total coloring of G is called adjacent-distinguishing if for arbitrary two adjacent vertices u and υ , C(u) :/= C(υ) ,where C(u) is the set of the colors of u and edges which is adjacent to u. The minimum k such that G(V,E) has ak- adjacent-vertex-distinguishing total coloring is called the adjacent-vertex-distinguishing total chromatic number. The adjacent-vertexdistinguishing total chromatic number on the Cartesion product of circle Cm and complete graph Kn (Cn × Kn )is obtained.
Keywords:graph  total coloring  adjacent-vertex-distinguishing total coloring  adjacent-vertex-distinguishing total chromatic number
