Strict comparison for -algebras arising from Almost finite groupoids
Pere Ara, Christian Bönicke, Joan Bosa +1
In this paper we show that for an almost finite minimal ample groupoid , its reduced -algebra has real rank zero and strict comparison even though $C_r^…

The type semigroup, comparison and almost finiteness for ample groupoids
Pere Ara, Christian Bönicke, Joan Bosa +1
We prove that a minimal second countable ample groupoid has dynamical comparison if and only if its type semigroup is almost unperforated. Moreover, we investigate to what extent a…
