Tile ℤ2 with translations of one set
Hui Rao, Yu-mei Xue
Abstract
Let A be a finite subset of
ℤ2. We say A tiles
ℤ2 with the translation set
C, if any integer z∈ℤ2
can be represented as z1+z2,
z1∈ A, z2∈ C
in an unique way. In this case we call A a
ℤ2-tile and write
A ⊕ C = ℤ2.
A tile A is said to be a normal
ℤ2-tile if there exists a periodic set
C such that
A ⊕ C = ℤ2. We characterize all normal
ℤ2-tiles with prime cardinality.
