摘要
The invariances of certain class of cut and project quasicrystals under rescalings (inflations) are investigated. All centers of self-similarities of this type are described, both being quasicrystal points, or not. For any such an "inflation center" we determine the set of relevant scaling factors. In analogy to the quasiaddition of Berman and Moody, we introduce other binary operations, under which a quasicrystal point set is invariant.
