Abstract

We construct an increasing sequence of natural numbers with the property that is dense in for any , and a continuous measure on the circle such that . Moreover, for every fixed , the set is infinite. This is a sufficient condition for the existence of a rigid, weakly mixing dynamical system whose rigidity time is not a rigidity time for any system with a discrete part in its spectrum.
