Free actions of polynomial growth Lie groups and classifiable C*-algebras
Ulrik Enstad, Gabriel Favre, Sven Raum
We show that any free action of a connected Lie group of polynomial growth on a finite dimensional locally compact space has finite tube dimension. This is shown to imply that the…

A note on inner amenability for FLC point sets
Gabriel Favre
Inner amenability is a bridge between amenability of an object and amenability of its operator algebras. It is an open problem of Ananantharman-Delaroche to decide whether all étal…

An algebraic characterization of ample type I groupoids
Gabriel Favre, Sven Raum
We give algebraic characterizations of the type I and CCR properties for locally compact second countable, ample Hausdorff groupoids in terms of subquotients of their Boolean inver…
