摘要
Let S be a bounded, Riemann measurable set in R-d, and Lambda be a lattice. By a theorem of Fuglede, if S tiles R-d with translation set Lambda, then S has an orthogonal basis of exponentials. We show that, under the more general condition that S multi-tiles R-d with translation set Lambda, S has a Riesz basis of exponentials. The proof is based on Meyer's quasicrystals.
