毕达哥拉斯三元组、复数、阿贝尔群和素数

Pythagorean Triples, Complex Numbers, Abelian Groups and Prime Numbers

Amnon Yekutieli

摘要:

众所周知,勾股三元组可以用具有有理坐标的单位圆上的点来表示。这些点形成一个阿贝尔群,我们描述它的结构。这种结构的描述产量,几乎立即,枚举规范化的勾股三元组与给定的cross-use,也到一个有效的方法,生产所有这样的三元组。这种有效的方法似乎是新的。这篇论文是为一般数学观众,包括本科数学学生,因此它包含了大量的背景材料,一些历史和几个例子和练习。

英文摘要:

It is well-known that pythagorean triples can be represented by points of the unit circle with rational coordinates. These points form an abelian group, and we describe its structure. This structural description yields, almost immediately, an enumeration of the normalized pythagorean triples with a given hypotenuse, and also to an effective method for producing all such triples. This effective method seems to be new. This paper is intended for the general mathematical audience, including undergraduate mathematics students, and therefore it contains plenty of background material, some history and several examples and exercises.
