Abstract


Three topics in dynamical systems are discussed. First we deal with cascades and solve two open problems concerning, respectively, product recurrence, and uniformly rigid actions. Next we provide a new example that displays some unexpected properties of strictly ergodic actions of non-amenable groups.

Keywords


Product recurrence; double minimality; uniform rigidity; measure weak mixing; strict ergodicity; amenability
