Abstract: We discuss the stable ergodicity of the action of groups of diffeomorphisms on a smooth manifold. We provide a mechanism, called quasi conformal blender, to overcome the higher dimensions restrictions for constructing stably ergodic actions. In particular, we prove that every closed manifold admits stably ergodic finitely generated group actions by smooth diffeomorphisms.
