Variations on a theme of Beurling.
On quasi-free Hilbert modules.
Hilbert C*-modules and amenable actions
We study actions of discrete groups on Hilbert C*-modules induced from topological actions on compact Hausdorff spaces. We show non-amenability of actions of non-amenable and non-a-T-menable groups, provided there exists a quasi-invariant probability measure which is sufficiently close to being invariant.
