摘要
定义一个集合Rn(x)并利用域R的两个运算引进了Rn(x)上的一个运算*.证明了(Rn(x),*)是交换群并给出几个特殊的正规子群,最后给出了Rn(x)的商群与加群R以及Rn(x)的商群与乘群R\{0}之间的关系.
Rn (x) is defined as a set, and an operation * onRn (x) is introduced by using two operations on fieldR. (Rn(x), * ) is proved to be a commutative group and several special normal subgroups are given. Finally, relationship between the quotient group of Rn (x) and the additive group R and relationship between the quotient group of Rn (x) and the product group R/{0} are given.
