摘要
本文引进了群上同余的概念 ,得到了群上的等价关系为群上同余的一个充分必要条件 。
In this paper,we introuduce congruence on group and get a necessary and sufficient condition for equivalence relation on group being a congruence on group.We also discuss the interrelation between congruence on group and the normal subgroup of group as well as the interrelation between congruence on group and homomorphism on group.
