摘要： 利用色集合事先分配法及具体的染色给出了mC7的最优点可区别Ⅰ-全染色以及最优点可区别Ⅵ-全染色,进而确定了图mC7的点可区别Ⅰ-全色数及点可区别Ⅵ-全色数。结论表明VDITC猜想和VDVITC猜想对图mC7成立。

Abstract: By using the methods of constructing a matrix which was composed of color sets and empty set as the elements, distributing color sets in advance and coloring explicitly, to give the optimal vertex distinguishing Ⅰ-total colorings and the optimal vertex distinguishing Ⅵ-total colorings of mC7. Thus vertex distinguishing Ⅰ-total chromatic numbers and the vertex distinguishing Ⅵ-total chromatic numbers of mC7 are determined. The results show that the VDITC conjecture and VDVITC conjecture are valid for mC7.

Key words: cycle, disjoint union, vertex-distinguishing Ⅰ-total coloring, vertex-distinguishing Ⅵ-total coloring, vertex-distinguishing Ⅰ-total chromatic number, vertex-distinguishing Ⅵ-total chromatic number
