本原几乎勾股三元组群

The Group of Primitive Almost Pythagorean Triples

Nikolai A. Krylov, Lindsay M. Kulzer

摘要:

我们考虑整数的三元组是方程$x^2+qy^2=z^2$的解,其中$q$是固定的、无平方的任意正整数。在复乘的运算下,这些三元组的等价类的集合形成一个阿贝尔群。我们研究了这个群的代数结构,并给出了当$q\in\{2,3,5,6\}$。

英文摘要:

We consider the triples of integer numbers that are solutions of the equation $x^2+qy^2=z^2$, where $q$ is a fixed, square-free arbitrary positive integer. The set of equivalence classes of these triples forms an abelian group under the operation coming from complex multiplication. We investigate the algebraic structure of this group and give a complete analysis when $q\in\{2,3,5,6\}$.
