Title: Cocycles of Ergodic Hyperfinite Equivalence Relations
Abstract: I will discuss a strengthening of Dye's Theorem first proved by Golodets and Sinel'shchikov in their paper "Classification and Structure of Cocycles of Amenable Ergodic Equivalence Relations," and also studied in a paper of Danilenko, e.g., "Quasinormal Subrelations of Ergodic Equivalence Relations." The relevant theorem in each paper is [G-S Lemma 1.12] and [D Theorem 1.9].
