Abstract

Given a G-flow X, let $\mathrm{Aut}(G, X)$, or simply $\mathrm{Aut}(X)$, denote the group of homeomorphisms of X which commute with the G action. We show that for any pair of countable groups G and H with G infinite, there is a minimal, free, Cantor G-flow X so that H embeds into $\mathrm{Aut}(X)$. This generalizes results of [2, 7].
