摘要:A recent result of Brown, Rodriguez Hertz and myself states that smooth Anosov actions by higher rank lattices on tori and nilmanifolds are smoothly conjugate to affine actions under a lifting hypothesis. In this talk, we will explain why continuous action by higher rank lattices on tori and nilmanifolds are continuously semiconjugate to affine actions, without assuming either hyperbolicity or lifting. This is a joint work with F. Rodriguez Hertz.
