For each connected component of the space of real-analytic Anosov diffeomorphisms on a real-analytic manifold, we prove a dichotomy: either the exponent $d$ in our bound is never optimal, or it is optimal on a dense subset. Using examples constructed by Bandtlow, Just and Slipantschuk, we see that we are always in the latter situation for connected components of the space of real-analytic Anosov diffeomorphisms on the $2$-dimensional torus.", "revisions": [ { "version": "v1", "updated": "2022-12-19T22:00:43.000Z" } ], "analyses": { "subjects": [ "37C30", "37D20" ], "keywords": [ "real-analytic anosov diffeomorphisms", "ruelle resonances", "distribution", "connected component", "dimensional torus" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
