7 . 对称变换在对称数学中具有重要的研究意义.若一个平面图形K在m(旋转变换或反射变换)的作用下仍然与原图形重合,就称K具有对称性,并记m为K的一个对称变换.例如,正三角形R在
(绕中心O作120°的旋转)的作用下仍然与R重合(如图1图2所示),所以
是R的一个对称变换,考虑到变换前后R的三个顶点间的对应关系,记
;又如,R在
(关于对称轴
所在直线的反射)的作用下仍然与R重合(如图1图3所示),所以
也是R的一个对称变换,类似地,记
.记正三角形R的所有对称变换构成集合S.一个非空集合G对于给定的代数运算.来说作成一个群,假如同时满足:
I.
,
;
II.
,
;
Ⅲ.
,
,
;
Ⅳ.
,
,
.
对于一个群G,称Ⅲ中的e为群G的单位元,称Ⅳ中的
为a在群G中的逆元.一个群G的一个非空子集H叫做G的一个子群,假如H对于G的代数运算
来说作成一个群.
(2)同一个对称变换的符号语言表达形式不唯一,如
.对于集合S中的元素,定义一种新运算*,规则如下:
,
.
①证明集合S对于给定的代数运算*来说作成一个群;
②已知H是群G的一个子群,e,
分别是G,H的单位元,
,
,
分别是a在群G,群H中的逆元.猜想e,
之间的关系以及
,
之间的关系,并给出证明;
③写出群S的所有子群.
