That is, we remove a hyperplane arrangement from complex hyperbolic $13$-space, take the quotient of the remaining space by a discrete group, and find generators for the orbifold fundamental group of the quotient. These generators have the most natural form: loops corresponding to the hyperplanes which come nearest the basepoint. Our results support the conjecture that motivated this study, the \"monstrous proposal\", which posits a relationship between this braid group and the monster finite simple group.", "revisions": [ { "version": "v1", "updated": "2017-02-19T06:47:02.000Z" } ], "analyses": { "subjects": [ "57M05", "20F36", "52C35", "32S22" ], "keywords": [ "complex hyperbolic braid group", "generators", "monster finite simple group", "orbifold fundamental group", "discrete group" ], "note": { "typesetting": "TeX", "pages": 46, "language": "en", "license": "arXiv", "status": "editable" } } }
