“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}).
