a而在抽象代数中,我们研究子群和不变子群,并通过陪集和商群的引入简化其代数结构 But in the abstract algebra, we studies the subgroup and the normal divisor, and simplifies its algebra structure through the coset and the quotient group introduction[translate]...

,是正规子群的定义,这意味着 ,从而可以不用区分左右陪集。从而 ,这就是商群的定义——将每个 陪集作为一个元素,记作 。 这件事可以用映射来表达 ,更一般的对于任何映射都可以表示为: ,子群的结构其实是分层的: ,在 的作用下, 。一般教科书上还会给出另外两个同构定理,都可以作为习题自己写出来。
In [6] it was formalized that the direct product of a family of groups gives a new group. In this article, we formalize that for all j ∈ I, the group G = Πi∈IGi has a normal subgroup isomorphic to Gj. Moreover, we show some relations between a family of groups and its ...

In this paper, we study the notion of normal L -subgroup of an L -group and provide its characterization by an L -point. We also provide a construction of the normalizer of an L -subgroup of a given L -group by using L -points. Moreover, we also discuss the product, homomorphic im...
An abelian subgroup H of a finite group G is said to be a maximal abelian subgroup in G if its centralizer is just itself.Finite groups in which every non-maximal abelian subgroup is normal are investigated,and then the classification of this kind groups is given in this paper.关键词:finit...
