Groups with rapid decay and trivial amenable radical are C*-simple

Caleb Barnett, Joseph Gondek, Mehrdad Kalantar

We prove that every finitely generated group with rapid decay and trivial amenable radical is C*-simple.

Simplicity and pure infiniteness for $C^{*}$ -algebras associated with stabilizers of boundary actions

Felipe Flores, Joseph Gondek

Given a discrete group $Γ$ acting on a compact space $X$ , and a stabilizer subgroup $Λ \leq Γ$ of $X$ , we use the Rieffel induction of covariant $(Λ, X)$ -representations to study cl…

Growth conditions for topological freeness

Nazmul Alam, Joseph Gondek, Mehrdad Kalantar +1

Given a finitely generated group $Γ$ , a non-trivial element $g \in Γ$ , and a minimal action $Γ ↷ X$ on a compact space $X$ , with amenable neighborh…

The action of an inverse semigroup on its Stone-Čech compactification

Joseph P. Z. Gondek, Charles Starling

We initiate the study of the Stone-Čech transformation groupoid $G = S ⋉ β S$ of an inverse semigroup $S$ . We prove that the properties o…
