In this paper, we do \\textit{not} assume $f$ is $\\mathcal{C}^1$-generic. We have two main themes in the paper: (1) the chain recurrence; (2) relations among recurrence points, homoclinic points, shadowability and hyperbolicity. For (1) (without assuming $M$ is compact), we have the theorem: if $f$ is Lagrange stable, then $M$ is a chain recurrent set. If $M$ is compact, then the Lagrange-stability is automatic. For (2) (assuming the compactness of $M$), we prove some various implications among notions, such as: (i) the $\\mathcal{C}^1$-stable shadowability equals to the hyperbolicity of $M$; (ii) if a point $p\\in M$ has a recurrence point in the unstable manifold $W^u (p, f)$ and there is no homoclinic point of $p,$ then $f$ is nonshadowable; (iii) if $f$ has the shadowing property and $p$ has a recurrence point in $W^u (p, f),$ then the recurrent point is in the limit set of homoclinic points of $p$.", "revisions": [ { "version": "v1", "updated": "2009-04-07T13:45:22.000Z" } ], "analyses": { "subjects": [ "37C50", "37C29", "37D05" ], "keywords": [ "homoclinic point", "chain recurrence", "volume-preserving diffeomorphisms", "recurrence point", "genericity" ], "note": { "typesetting": "TeX", "pages": 17, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2009arXiv0904.1142C" } } }
