In this paper it is shown that both of them have the homotopy type of a sphere of dimension $n-d-3$. Moreover, we resolve positively a new special case of the \\emph{Generalized Baues Problem}: The Baues poset of all polytopal decompositions of a cyclic polytope of dimension $d \\leq 3$ has the homotopy type of a sphere of dimension $n-d-2$.", "revisions": [ { "version": "v1", "updated": "1997-04-08T00:00:00.000Z" } ], "analyses": { "keywords": [ "cyclic polytope", "subdivision posets", "homotopy type", "higher stasheff-tamari orders", "related poset structures" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "1997math......4217E" } } }
