- primitive Pythagorean number 本原商高数
- In this paper,we proposed the average order of the Primitive Pythagorean triplets on Diophantine equation a+4+b+2=c+2, and presented one asymptotic estimation formula. 研究了不定方程 a4+b2 =c2 的整数解的组数 ;并得到它的一个渐近估计式 .
- Let(a,b,c) be a primitive Pythagorean triple with a is even. In this paper we prove that if c is a prime power,then the equation x~2+b~y=c~z has only the positive integer solution(x,y,z)=(a,2,2) with y is even. 设(a;b;c)是一组适合a为偶数的本原商高数;该文证明了:当c是素数方幂时;方程x2+by=cz仅有正整数解(x;y;z)=(a;2;2)可使y是偶数.
- Furthermore by some skills of algebra, it is proved that the set of all pythagorean number matrixes is a finitely generated group, and a set of generators of the finitely generated group is given. 利用相关代数技巧，证明由所有的勾股矩阵构成的集合T是一个关于矩阵乘法的有限生成群。同时，给出该有限生成群的一个生成元组。
