摘要

在这篇短文中,我们构造了(Z/pZ)4(\mathbb{Z}/p\mathbb{Z})^4pp为奇素数)中大小为2p2p的谱非平铺集。该例子补充了[arXiv:1509.01090]中先前的反例,后者仅存在于p3(mod4)p \equiv 3 \pmod{4}的情形。相反,我们证明该猜想在(Z/2Z)4(\mathbb{Z}/2\mathbb{Z})^4中成立。

备注

This result was found simultaneously and independently with [arXiv:1901.08734]. However, it contained an error which was fixed afterwards (again independently). We record it here as it gives a more geometrical approach to more or less the same construction
