摘要
运用初等变换方法和四元数范数性质,得到一个正整数可写成四个正整数的平方和的几个判别条件;还证明了若两个整数可写成四个正整数的平方和,则它们的乘积也可写成另外四个正整数的平方和,并给出相应的算法.
In this norm, we got a few square. Finite positive can be written as sum paper, using elementary transformation method and properties of quaternion diseriminant conditions of a positive integer written as four positive integer integer can be expressed as sum of four positive integer square, and its product of four positive integer square.
