摘要
分别研究了F(C7C3)的单位群结构,其中F是有限域;FG的单位群结构,其中G是21阶的非交换群,F是特征不等于3,7的有限群.
In this paper, the structure of the unit group of F（C7 X C3 ） over any finite field is established; the structure of the unit group of FG of the non-abelian group G with order 21 over any finite field of characteristic p：;~ 3,7 is also established.
