子群

假设(G, *)是一个群,若 HG 的一个非空子集且同时 H 与相同的二元运算 * 亦构成一个群,则 (H, *) 称为 (G, *) 的一个子群。参阅群论。

更精确地来说,HG的子群若运算*在H的限制也是个在H上的群运算的话。

一个群G纯子群是指一个子群H,其为G的纯子集(即HG)。任一个群的当然群为只包含单比特素的子群{e}。若HG的子群,则G有时会被称为H的「母群」。

相同的定义可以应用在更广义的范围内,当G为一任意的半群,但此一条目中只处理群的子群而已。群G有时会被标记成有序对(G,*),通常用以强调其运算*当G带有多重的代数或其他结构。

The symmetric group S4 showing all permutations of 4 elements
Hasse diagram of the lattice of subgroups of S4

In group theory, a branch of mathematics, given a group G under a binary operation ∗, a subset H of G is called a subgroup of G if H also forms a group under the operation ∗. More precisely, H is a subgroup of G if the restriction of ∗ to H × H is a group operation on H. This is usually denoted HG, read as "H is a subgroup of G".
