周期平铺猜想的一个反例(公告)
A counterexample to the periodic tiling conjecture (announcement)
摘要:
周期性平铺猜想断言,格$\mathbb{Z^d}$的任何有限子集通过平移平铺该格,实际上是周期性地平铺。我们在这里宣布这个猜想的反证足够大的$d$,这也意味着相应的猜想为欧几里得空间$\mathbb{R^d}$反证。事实上,我们也得到了一个反例在一个群的形式$\mathbb{Z^2} \times G_0$的某些有限交换$G_0$。我们的方法依赖于编码的“$p$ -adically结构的功能”在某些函数方程的某一类。
英文摘要:
The periodic tiling conjecture asserts that any finite subset of a lattice $\mathbb{Z^d}$ which tiles that lattice by translations, in fact tiles periodically. We announce here a disproof of this conjecture for sufficiently large $d$, which also implies a disproof of the corresponding conjecture for Euclidean spaces $\mathbb{R^d}$. In fact, we also obtain a counterexample in a group of the form $\mathbb{Z^2} \times G_0$ for some finite abelian $G_0$. Our methods rely on encoding a certain class of "$p$-adically structured functions" in terms of certain functional equations.
