چکیده
1. Lenz and Stollman [3] pointed out that the “metric” ρ defined on page 266 of [4] does not satisfy the triangle inequality. There we used for two Delone sets Λ1 and Λ2, denoting by Br the ball of radius r centered at the origin: ρ(Λ1,Λ2) = min{2−1/2, ρ̃(Λ1,Λ2)}, where ρ̃(Λ1,Λ2) = inf{ > 0 : dH [Λ1 ∩B1/ , Λ2 ∩B1/ ] ≤ } . Here dH is the Hausdorff distance. There are several ways to fix this, described in [3]. Alternatively, we can consider

Spectrum of dynamical systems arising from Delone sets
We investigate spectral properties of the translation action on the orbit closure of a Delone set. In particular, suucient conditions for pure discrete spectrum are given, based on the notion of almost periodicity. Connections with diiraction spectrum are discussed.
متن کاملEquicontinuous Delone Dynamical Systems
We characterize equicontinuous Delone dynamical systems as those coming from Delone sets with strongly almost periodic Dirac combs. Within the class of systems with finite local complexity the only equicontinuous systems are then shown to be the crystalline ones. On the other hand, within the class without finite local complexity, we exhibit examples of equicontinuous minimal Delone dynamical s...

This mini-workshop brought together researchers with diverse backgrounds and a common interest in facets of the Pisot conjecture, which relates certain properties of a substitution to dynamical properties of the associated subshift. Mathematics Subject Classification (2000): 37B10, 28A80, 37B50, 52C23. Introduction by the Organisers A substitution is a non-erasing morphism of the free monoid. S...
متن کاملPure Point Diffractive Substitution Delone Sets Have the Meyer Property Jeong-yup Lee and Boris Solomyak
We prove that a primitive substitution Delone set, which is pure point diffractive, is a Meyer set. This answers a question of J. C. Lagarias. We also show that for primitive substitution Delone sets, being a Meyer set is equivalent to having a relatively dense set of Bragg peaks. The proof is based on tiling dynamical systems and the connection between the diffraction and dynamical spectra.
