As an application we describe the ending lamination set for a hyperbolic extension of $\\mathbb{F}$ by a hyperbolic subgroup of $\\mathsf{Out(\\mathbb{F})}$ in a new way and use it to prove results about Cannon-Thurston maps for such extensions. We also use it to derive conditions for quasiconvexity of finitely generated, infinite index subgroups of $\\mathbb{F}$ in the extension group. These results generalize similar results obtained by Mahan Mj, Kapovich-Lustig and use different techniques.", "revisions": [ { "version": "v1", "updated": "2017-09-23T07:31:32.000Z" } ], "analyses": { "subjects": [ "20F65" ], "keywords": [ "conjugacy class", "hyperbolic elements", "results generalize similar results", "infinite index subgroups", "lamination set" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
