Frames Generated by Actions of Countable Discrete Groups
We consider dual frames generated by actions of countable discrete groups on a Hilbert space. Module frames in a class of modules over a group algebra are shown to coincide with a class of ordinary frames in a representation of the group. This has applications to shift-invariant spaces and wavelet theory. One of the main findings in this paper is that whenever a shift-invariant subspace in L2(R...
متن کاملUniversal Borel Actions of Countable Groups
If the countable group G has a nonabelian free subgroup, then there exists a standard Borel G-space such that the corresponding orbit equivalence relation is countable universal. In this paper, we will consider the question of whether the converse also holds.
متن کاملExpansive algebraic actions of countable abelian groups
This paper gives an algebraic characterization of expansive actions of countable abelian groups on compact abelian groups. This naturally extends the classification of expansive algebraic Zd-actions given by Schmidt using complex varieties. Also included is an application to a natural class of examples arising from unit subgroups of integral domains. 2000 Mathematics Subject Classification: 22D...
متن کاملMf-property for Countable Discrete Groups
In this article we study MF-property for countable discrete groups, i.e. groups which admit embedding into unitary group of C∗-algebra ∏ Mn/ ⊕ Mn. We prove that Baumslag group 〈a, b|aab = a2〉 has MF-property and check some permanent facts about MF-groups.
متن کاملErgodic Actions of Countable Groups and Finite Generating Partitions
We prove the following finite generator theorem. Let G be a countable group acting ergodically on a standard probability space. Suppose this action admits a generating partition having finite Shannon entropy. Then the action admits a finite generating partition. We also discuss relationships between generating partitions and f-invariant and sofic entropies.
