Let $P(t)$ be the set of free-homotopy classes containing a closed geodesic on $M$ with length at most $t$, and $\\# P(t)$ its cardinality. We obtain the following Margulis-type asymptotic estimates: \\[\\lim_{t\\to \\infty}\\#P(t)/\\frac{e^{ht}}{ht}=1\\] where $h$ is the topological entropy of the geodesic flow. In the appendix, we also show that the unique measure of maximal entropy of the geodesic flow has the Bernoulli property.", "revisions": [ { "version": "v1", "updated": "2021-05-05T02:28:47.000Z" } ], "analyses": { "keywords": [ "counting closed geodesics", "focal points", "geodesic flow", "margulis-type asymptotic estimates", "free-homotopy classes" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
