Expansive algebraic actions of countable abelian groups
نویسنده
چکیده
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: 22D40, 37B05, 13A18, 13G05.

Homoclinic Groups, Ie Groups, and Expansive Algebraic Actions
We give algebraic characterizations for expansiveness of algebraic actions of countable groups. The notion of p-expansiveness is introduced for algebraic actions, and we show that for countable amenable groups, a finitely presented algebraic action is 1-expansive exactly when it has finite entropy. We also study the local entropy theory for actions of countable amenable groups on compact groups...

متن کاملThe Adjoint Action of an Expansive Algebraic Z–Action
Let d ≥ 1, and let α be an expansive Z-action by continuous automorphisms of a compact abelian group X with completely positive entropy. Then the group ∆α(X) of homoclinic points of α is countable and dense in X, and the restriction of α to the α-invariant subgroup ∆α(X) is a Z-action by automorphisms of ∆α(X). By duality, there exists a Z-action α∗ by automorphisms of the compact abelian group...

An irreducible algebraic Z d-action on a compact abelian group X is a Z d-action by automorphisms of X such that every closed,-invariant subgroup Y (X is nite. We prove the following result: if d 2, then every measurable conjugacy between irreducible and mixing algebraic Z d-actions on compact zero-dimensional abelian groups is aane. For irreducible, expansive and mixing algebraic Z d-actions o...
متن کاملIrreducibility, Homoclinic Points and Adjoint Actions of Algebraic Z–Actions of Rank One
In this paper we consider Z-actions, d ≥ 1, by automorphisms of compact connected abelian groups which contain at least one expansive automorphism (such actions are called algebraic Z-actions of expansive rank one). If α is such a Z-action on an infinite compact connected abelian group X, then every expansive element α of this action has a dense group ∆αn(X) of homoclinic points. For different ...
