Some Properties of Lattice Substitution Systems
Dirk Frettlöh
Abstract
If a partition of a lattice in Rd is selfsimilar, it is called lattice substitution system (LSS). Such sets represent nonperiodic, but highly ordered structures. An important property of such structures is, whether they are model sets or not (equivalently, whether they are pure point diffractive or not). In this paper two conditions are given, which can be used to show that a given lattice substitution system does not consist of model sets.
