Query: Dynamical properties of almost repetitive Delone sets   We consider the collection of uniformly discrete point sets in Euclidean
space equipped with the vague topology. For a point set in this collection, we
characterise minimality of an associated dynamical system by almost
repetitivity of the point set. We also provide linear versions of almost
repetitivity which lead to uniquely ergodic systems. Apart from linearly
repetitive point sets, examples are given by periodic point sets with almost
periodic modulations, and by point sets derived from primitive substitution
tilings of finite local complexity with respect to the Euclidean group with
dense tile orientations.
