摘要
对一般的群来说,很难找到一个结构简单且具体的群与其等价.文章主要研究了商群Zm×Zn/N,其中N为正规子群,分别给出了商群Zm×Zn/N在满足条件gcd(m,n)=1和gcd(m,n)≠1(m为素数)情形下的等价群.
For the general group,it is not easy to find a simple and concrete group to characterize it.In this paper,we consider the quotient group Zm×Zn/N with normal subgroup N and give its equivalence for the cases gcd(m,n)=1 and gcd(m,n)≠1(m is prime),respectively.
