Abstract:Abstract.Let 3? denote the group of all automorphisms of a finite Lebesgue space equipped with the weak topology. For T e S£ , let 177-denote its maximal spectral type.
“…The disjointness of the convolution powers follows from α-weakly mixing property when 0 < α < 1 (see [6] and [7]). This property is widely used in ergodic theory to build counterexamples ( [8]). The question of α-weak mixing for Chacon's automorphism can be considered as a special case of the general problem of description of the weak limits of powers ofT .…”
“…The main spectral property of a generic T ∈ Aut(X, µ) is given by Del Junco-Lemańczyk [3] where Aut(X, µ) is the set of all measure preserving transformations on a Borel measure space (X, µ). They proved that for a generic T ∈ Aut(X, µ), for every k(1), k(2), .…”

Del Junco-Lemańczyk [3] showed that a generic measure preserving transformation satisfies a certain orthogonality conditions. More precisely,
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
