A generic $C^1$ map has no absolutely continuous invariant probability measure

摘要

Let MM be a smooth compact manifold (maybe with boundary, maybe disconnected) of any dimension d1d \ge 1. We consider the set of C1C^1 maps f:MMf:M\to M which have no absolutely continuous (with respect to Lebesgue) invariant probability measure. We show that this is a residual (dense Gδ)setintheG_\delta) set in the C^1$ topology. In the course of the proof, we need a generalization of the usual Rokhlin tower lemma to non-invariant measures. That result may be of independent interest.
