Abstract (EN)Given any self-similar quasicrystal Λ in Rn with inflation θ>1, we construct bases of L2(Rn) having the following structure: θnj/2ψλ(θjx−λ), λ ∊ ΛθΛ, j ∊ Z, where the mother wavelets ψλ, λ ∊ ΛθΛ, are smooth and with exponential decay or compact support. We also show that wavelets ψλ constitute a relatively compact set in some Sobolev space and that they depend continuously on λ when Λ is equipped with an appropriate topology.
