Résume | Smooth Orbit Equivalence (SOE) is an orbit equivalence relation between free ℝᵈ-flows that acts by diffeomorphisms between orbits. This idea originated in ergodic theory of ℝ-flows under the name of time-change equivalence, where it is closely connected with the concept of Kakutani equivalence of induced transformations. When viewed from the ergodic theoretical viewpoint, SOE has a rich structure in dimension one, but, as discovered by Rudolph, all ergodic measure-preserving ℝᵈ-flows, d > 1, are SOE.
