The periodic tiling conjecture for finite subsets of finitely generated Abelian groups
Let be a finitely generated Abelian group and let be a finite subset of . A tiling of by is a set such that
A tiling is periodic if its translation set is invariant under translations by a finite-index subgroup of .
Periodic tiling conjecture. The tiling equation is not aperiodic; equivalently, whenever tiles by translations, it admits at least one periodic tiling.
This conjecture concerns whether every translational tiling by a finite tile has a periodic realization. Its status is not specified in the source.
