We also produce a sub-class admitting arbitrarily many distinct tight contact structures within the same homotopy class of oriented plane distributions. We also introduce a notion of geometric limits of contact structures compatible with geometric limits of hyperbolic manifolds. We study the behavior of the tight contact structures we construct under geometric limits.", "revisions": [ { "version": "v1", "updated": "2024-04-23T02:56:46.000Z" } ], "analyses": { "subjects": [ "57R17", "57M50" ], "keywords": [ "hyperbolic homology", "distinct tight contact structures", "geometric limits", "large class", "oriented plane distributions" ], "note": { "typesetting": "TeX", "pages": 28, "language": "en", "license": "arXiv", "status": "editable" } } }
