中文摘要: |
设G为简单图.设f是图G的一个一般全染色,若对图G的任意两个不同的顶点u、v,有C(u)≠C(v),则称f为图G的一般点可区别全染色(简记为 GVDTC ).对图G进行一般点可区别全染色所需要的最少颜色数称为图G的一般点可区别全色数.将一类含有4-圈的单圈图悬挂边的染色按从小到大的顺序排列,探讨了它的一般点可区别全染色,确定了它具有一般点可区别全染色,并得到了它的一般点可区别全色数. |
英文摘要: |
Let G be a simple graph. For a general total coloring f of G , if C(u)≠C(v) for any two different vertices u and v of G , then f is called a general vertex-distinguishing total coloring of G (or GVDTC of G for short). The minimum number of colors required in a GVDTC is the general vertex-distinguishing total chromatic number. The general vertex-distinguishing total colorings of a family of unicyclic graphs including C 4 are discussed by making the coloring of its pendent edges in an ascending order. It is determined that it has a general vertex-distinguishing total coloring of G and its general vertex-distinguishing total chromatic number is got. |
