In particular, we show that it is Quillen equivalent to the models of $(\\infty,1)$-categories given by complete Segal spaces and Segal categories. We furthermore prove that this model structure has desirable properties: it is cartesian closed and left proper. As applications, we get a simple description of the inclusion of categories into $(\\infty,1)$-categories and of homotopy limits of $(\\infty,1)$-categories.", "revisions": [ { "version": "v1", "updated": "2024-12-13T18:52:37.000Z" } ], "analyses": { "subjects": [ "18N60", "55U35", "18N50" ], "keywords": [ "model structure", "complete segal spaces", "fibrant objects", "homotopy limits", "simplicial spaces" ], "note": { "typesetting": "TeX", "pages": 20, "language": "en", "license": "arXiv", "status": "editable" } } }
