Streszczenie

We introduce a property of ergodic flows, called Property B. We prove that an ergodic hyperfinite equivalence relation of type III$_{0}$ whose associated flow has this property is not of product type. A consequence is that a properly ergodic flow with Property B is not approximately transitive. We use Property B to construct a non-AT flow which—up to conjugacy—is built under a function with the dyadic odometer as base automorphism.
