摘要: 首先, 通过引入群的分配子概念, 给出群分配子的若干性质; 其次, 对群论中换位子和p-换位子的相应结果进行推广, 并证明群G到群H的映射f为群同态当且仅当群G的f-分配子是1;最后, 作为应用, 计算出一类亚循环群到二面体群之间的同态个数.

关键词: 分配子, p-换位子, p-导群, 群同态

Abstract: Firstly, by introducing the notion of distributors of groups, we give some properties of distributors of groups. Secondly, we generalize  the corresponding results of commutators and p-commutators in group theory, and  prove that the mapping f from group G to group H is a group homomorphism if and only if the f-distributor of group G is 1. Finally, as an application, we calculate the number of homomorphisms from a class of metacyclic groups to dihedral groups.

Key words: distributor, p-commutator, p-derived group, group homomorphism
