Its structure depends on the combinatorial type of the complex. In this way, each closed orientable 3-manifold arises as a branched covering over the 3-sphere from some triangulation of S^3. This result is related to a theorem of Hilden and Montesinos. The branched coverings introduced admit a rich theory in which the group of projectivities plays a central role.", "revisions": [ { "version": "v2", "updated": "2002-03-20T08:59:55.000Z" } ], "analyses": { "subjects": [ "57M12", "57M25", "57Q99", "05C15", "05C10" ], "keywords": [ "branched covering", "triangulation", "structure depends", "central role", "simplicial complex" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2001math......8202I" } } }
