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构造具体染色的方法, 解决了图mC15的最优点可区别Ⅰ-全染色及最优点可区别Ⅵ-全染色问题, 得到了图mC15的点可区别Ⅰ-全色数和点可区别Ⅵ-全色数. 结果表明, 点可区别Ⅰ-全染色猜想和点可区别Ⅵ-全染色猜想对图mC15成立.

关键词: 点可区别Ⅰ-全染色, 点可区别Ⅵ-全染色, 点可区别Ⅰ-全色数, 点可区别Ⅵ-全色数

Abstract: We solved the problems of the optimal vertex-distinguishing Ⅰ-total colorings (VDITC) and the optimal vertex-distinguishing Ⅵ-total colorings (VDVITC) of graph mC15 by constructing a matrix with color sets and empty set as its elements, and using the methods of distributing color sets in advance and describing coloring explicitly, and obtained vertex-distinguishing Ⅰ-total chromatic numbers and the vertex-distinguishing Ⅵ-total chromatic numbers of graph mC15. The results  show that the VDITC conjecture and VDVITC conjecture are valid for graph mC15.

Key words: vertex-distinguishing Ⅰ-total colorings, vertex-distinguishing Ⅵ-total colorings, vertex-distinguishing Ⅰ-total chromatic numbers, vertex-distinguishing Ⅵ-total chromatic numbers
