Restricted Permutations and Permanents of Infinite Amenable Groups

Hanfeng Li, Klaus Schmidt

Let $Γ$ be an infinite discrete group and $A \subset Γ$ a nonempty finite subset. The set of permutations $σ$ of $Γ$ such that $s^{- 1} σ (s) \in A$ for every $s \in Γ$ …

Intrinsic Ergodicity, Generators and Symbolic Representations of Algebraic Group Actions

Hanfeng Li, Klaus Schmidt

We construct natural symbolic representations of intrinsically ergodic, but not necessarily expansive, principal algebraic actions of countably infinite amenable groups and use the…
