Abstract

Given a dynamical simplex KK on a Cantor space XX, we consider the set GKG_K^* of all homeomorphisms of XX which preserve all elements of KK and have no nontrivial clopen invariant subset. Generalising a theorem of Yingst, we prove that for a generic element gg of GKG_K^* the set of invariant measures of gg is equal to KK. We also investigate when there exists a generic conjugacy class in GKG_K^* and prove that this happens exactly when KK has only one element, which is the unique invariant measure associated to some odometer; and that in that case the conjugacy class of this odometer is generic in GKG_K^*.
