Given a finite group G and a positive integer r, an r-coloring of G is any mapping χ:G{1,,r}. Colorings χ and φ are equivalent if there exists gG such that χ(xg-1)=φ(x) for all xG. A coloring χ is symmetric if there exists gG such that χ(gx-1g)=χ(x) for every xG. We compute the number of symmetric r-colorings and the number of equivalence classes of symmetric r-colorings of an elementary Abelian p-group.

计算基本阿贝尔群的对称着色数

给定有限群G ^和一个正整数ř,一个R-着色ģ是任何映射χG{1个[R}。着色剂χφ如果存在则等效GG 这样 χg--1个=φX 对全部 XG。着色χ如果存在则对称GG 这样 χgx--1个G=χX 每一个 XG。我们计算基本abelian p-群的对称r-着色的数量和等价类的对称r-着色的数量。
