It contains enough information to define a classifying space which has many of the same properties as p-completed classifying spaces of finite groups. In this paper, we study and classify extensions of p-local finite groups, and also compute the fundamental group of the classifying space of a p-local finite group.", "revisions": [ { "version": "v1", "updated": "2005-02-16T17:47:15.000Z" } ], "analyses": { "subjects": [ "55R35", "55R40", "20D20" ], "keywords": [ "classifying space", "p-local finite group consists", "finite p-group", "fundamental group", "sylow p-subgroup" ], "tags": [ "journal article" ], "publication": { "publisher": "AMS", "journal": "Trans.
