We consider a class of compacta X such that the maps from X onto metric compacta define an Aronszajn tree of closed subsets of X.

In this article we collect a series of observations that constrain actions of many groups on compact manifolds. In particular, we show that “generic” finitely generated groups have no smooth volume preserving actions on compact manifolds while also producing many finitely presented, torsion free groups with the same property.
