Title: Mixing Properties and Comeager Subsets of Act(G,X,\mu)

Abstract: One of the early results in measurable dynamics, due to Halmos, is the fact that ergodic transformations form a comeager subset of the set of Aut(X,\mu). I will discuss several similar results when the group acting is not $\mathbb{Z}$. In particular, I will be concerned with groups that have property (T) or the Haagerup Approximation Property.
