Abstract
Quasicrystals can be characterized by a remarkable Diophantine approximation property. This permits to define the dual quasicrystal Λ* as the collection of y in ℝn such that |e iy·x−1| ≤ 1 for each x in the given quasicrystal Λ. In many cases one obtains Λ** = Λ and this duality is nicely related to the spectral properties of quasicrystals.
