Abstract

We consider systems of exponentials with frequencies belonging to simple quasicrystals in ℝd. We ask if there exist domains S in ℝd which admit such a system as a Riesz basis for the space L2 (S). We prove that the answer depends on an arithmetical condition on the quasicrystal. The proof is based on the connection of the problem to the discrepancy of multi-dimensional irrational rotations, and specifically, to the theory of bounded remainder sets. In particular it is shown that any bounded remainder set admits a Riesz basis of exponentials. This extends to several dimensions (and to the non-periodic setting) the results obtained earlier in dimension one.
