mathcal{Z}$-stability of crossed products by topological full groups

We introduce the property of having good subgroups for actions of countable discrete groups on compact metrizable spaces. We show that it implies comparison for actions of amenable groups and amenable actions of groups containing the free group on two generators. As a result, free actions on finite-...
