报告摘要:
We introduce a new criterion which guarantees that a conservative local diffeomorphism is both non-uniformly expanding and stably ergodic. The criterion involves averaging expansion rates over preimages and allows us to construct explicit examples in a variety of homotopy classes, including those represented by linear endomorphisms with contracting directions.
