摘要: 通过构造以色集合和空集为元素的矩阵, 利用色集合事先分配法及具体的染色方案, 给出图mC8的最优点可区别Ⅰ-全染色和最优点可区别Ⅵ-全染色, 进而确定图mC8的点可区别Ⅰ-全色数和点可区别Ⅵ-全色数. 结果表明, VDITC猜想和VDVITC猜想对图mC8成立.

Abstract: By constructing a matrix which was composed of color sets and empty set as the elements, using the distributing method of color sets in advance and specific coloring scheme, we gave the best vertex\|distinguishing Ⅰ-total colorings (VDITC) and the best vertex-distinguishing Ⅵ-total colorings  (VDVITC) of graph mC8. Thus vertex-distinguishing Ⅰ-total chromatic numbers and the vertex-distinguishing Ⅵ-total chromatic numbers of graph
mC8 were determined. The results show that the VDITC conjecture and VDVITC conjecture are valid for graph mC8.

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
