Mixing and tight polyhedra
Thomas Ward
Actions of by automorphisms of compact zero-dimensional groups exhibit a range of mixing behaviour. Schmidt introduced the notion of mixing shapes for these systems,…
Expansive algebraic actions of countable abelian groups
Richard Miles
This paper gives an algebraic characterization of expansive actions of countable abelian groups on compact abelian groups. This naturally extends the classification of expansive al…
Mixing actions of the rationals
Richard Miles, Tom Ward
We study mixing properties of algebraic actions of , showing in particular that prime mixing actions on connected groups are mixing of all orders, as is…
Isomorphism rigidity in entropy rank two
Manfred Einsiedler, Thomas Ward
We study the rigidity properties of a class of algebraic Z^3-actions with entropy rank two. For this class, conditions are found which force an invariant measure to be the Haar mea…
Periodic points for good reduction maps on curves
Manfred Einsiedler, Graham Everest, Thomas Ward
The periodic points of a morphism of good reduction for a smooth projective curve with good reduction over the p-adics form a discrete set. This is used to give an interpretation o…
Group automorphisms with few and with many periodic points
Thomas Ward
For any a compact group automorphism is constructed with the property that This may be…
