Topic:
Commuting Borel Automorphisms

Abstract:
We present a Kakutani Rokhlin tower construction for Borel automorphism group generated by two commuting Borel transformations of a standard Borel space. Using the Kakutani Rokhlin lemma we show that two commuting Borel automorphisms have the same set of real coboundaries if and only if either they are the same or are inverses of each other.
