利用(Z^2,+)同态生成互质整数对

On Using (Z^2, +) Homomorphisms to Generate Pairs of Coprime Integers

Brian A. Benson

摘要:

我们使用组$(\Z^2,+)$和两个相关的同态,$τ_0, τ_1$,以产生所有不同的,非零对互质,正整数,我们描述的范围内的二叉树,我们表示$T$。虽然这个想法与Stern-Brocot树和互素对映射有关,但这些树的整数对的父树不一定对应于$T$中同一整数对的父树。我们的主要结果是一个证明,对$x_i \in \{0,1\}$,$τ_{x_1}τ_{x_2}... τ_{x_n} [1,2]$的总和等于对$τ_{x_n}τ_{x_{n-1}} ... τ_{x_1} [1,2]$的总和。此外,我们给出了一个猜想,这些整数的和的良序。

英文摘要:

We use the group $(\Z^2,+)$ and two associated homomorphisms, $τ_0, τ_1$, to generate all distinct, non-zero pairs of coprime, positive integers which we describe within the context of a binary tree which we denote $T$. While this idea is related to the Stern-Brocot tree and the map of relatively prime pairs, the parents of an integer pair these trees do not necessarily correspond to the parents of the same integer pair in $T$. Our main result is a proof that for $x_i \in \{0,1\}$, the sum of the pair $τ_{x_1}τ_{x_2}... τ_{x_n} [1,2]$ is equal to the sum of the pair $τ_{x_n}τ_{x_{n-1}} ... τ_{x_1} [1,2]$. Further, we give a conjecture as to the well-ordering of the sums of these integers.
