Tiling with arbitrary tiles

Tiling with arbitrary tiles


Suppose that we have a tile (a finite subset of the grid Z^d for some d). It may or may not tile Z^d, meaning that we can partition Z^d into copies of it. But what about tiling a higher dimension? We show that, for every tile, there is some grid Z^m that it tiles. This resolves a conjecture of Chalcraft.
