Topic: 
Rokhlin-Lemma for Borel $Z^d$ actions and its application.

Abstract:
We prove Rokhlin-Lemma for $Z^d$ Borel actions. As an application we show that two commuting Borel transformations $S, T$ of a standard Borel space have same set of real coboundaries if and only if they are flip conjugate (i.e. $S$ is conjugate to $T$ or $S$ is conjugate to $T^{-1}$).
