关于虚二次数环中丢番图$m$ -元组的大小

On the size of Diophantine $m$-tuples in imaginary quadratic number rings

Nikola Adžaga

摘要:

丢番图$m$元组是一组$m$不同的整数,使得任何两个不同元素的乘积加一是完满平方。最近证明了在正整数中不存在丢番图五元组。我们在虚二次域的整数环中研究了同样的问题。通过使用间隙原理证明丢番图逼近,我们表明,$m\leqslant 42$。与正整数中类似结果的证明相比,我们的证明相对简单。

英文摘要:

A Diophantine $m$-tuple is a set of $m$ distinct integers such that the product of any two distinct elements plus one is a perfect square. It was recently proven that there is no Diophantine quintuple in positive integers. We study the same problem in the rings of integers of imaginary quadratic fields. By using a gap principle proven by Diophantine approximations, we show that $m\leqslant 42$. Our proof is relatively simple compared to the proofs of the similar results in positive integers.
