Abstract

Let  be an infinite subset of {1,2,…}. We characterize arithmetic and dynamical properties of the -free set  through group theoretical, topological and measure theoretic properties of a set W (called the window) associated with . This point of view stems from the interpretation of the set  as a weak model set. Our main results are:  is taut if and only if the window is Haar regular; the dynamical system associated to  is a Toeplitz system if and only if the window is topologically regular; the dynamical system associated to  is proximal if and only if the window has empty interior; and the dynamical system associated to  has the "na"ively expected" maximal equicontinuous factor if and only if the interior of the window is aperiodic.
