The manifold $\\Gamma\\backslash G$ is said to be modeled on the Lie group $G$. This class of manifolds is conjectured to be the only class of closed manifolds allowing an Anosov diffeomorphism. However, it is far from obvious which of these infra--nilmanifolds actually do admit an Anosov diffeomorphism. In this paper we completely solve this question for infra-nilmanifolds modeled on a free $c$--step nilpotent Lie group.", "revisions": [ { "version": "v2", "updated": "2014-05-13T07:12:08.000Z" } ], "analyses": { "keywords": [ "free nilpotent lie groups", "anosov diffeomorphism", "infra-nilmanifolds", "group acting", "step nilpotent lie group" ], "note": { "typesetting": "TeX", "pages": 19, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2013arXiv1304.6529D" } } }
