摘要: 运用分析法研究了直积图的邻点可区别E-全染色, 讨论了对于点色数至少为2以及邻点可区别E-全色数为3, 4的简单图的直积图的邻点可区别E-全色数, 并得出了一些相关推论.

关键词: 色数, 直积图, 邻点可区别E-全染色, 邻点可区别E-全色数

Abstract: By using of the analysis method, the adjacent vertex distinguishing E-total coloring of the cartesian product graphs are studied, and the adjacent vertex distinguishing E-total chromatic numbers for the cartesian products of the graphs with chromatic number at least 2 or the graphs with adjacent vertex distinguishing E-total chromatic numbers 3 or 4 are discussed, some relevant conclusions are also obtained.

Key words: the chromatic numbers, the cartesian product graph, the adjacent vertex distinguishing E-total coloring, the adjacent vertex distinguishing E-total chromatic number
