摘要: 利用群论与同余理论, 计算一类m阶循环群被4阶循环群扩张的亚循环群之间的同态个数, 并给出该类亚循环群的自同态个数. 所得结果验证了该类亚循环群满足Asai和Yoshida猜想.

关键词: 亚循环群, 同态, 自同态, 同余

Abstract: By using the group theory and congruence theory, we calculated the number of homomorphisms between a class of metacyclic groups, which were normal cyclic groups of the order m expanded by cyclic groups of the order 4, and gave the number of endomorphisms of the metacyclic groups. The results verified that the metacyclic groups satisfied the conjecture of Asai and Yoshida.

Key words: metacyclic group, homomorphism, endomorphism, congruence
