We show that the space of representations of the fundamental group of M into PSL(2,R) has exactly two connected components. These two components are the preimages of a certain Stiefel-Whitney characteristic class, computed in a similar way as the Euler class in the orientable case.", "revisions": [ { "version": "v1", "updated": "2009-09-13T15:27:47.000Z" } ], "analyses": { "subjects": [ "57M05", "57R20" ], "keywords": [ "connected components", "representation spaces", "stiefel-whitney characteristic class", "fundamental group", "compact closed non-orientable surface" ], "note": { "typesetting": "TeX", "pages": 18, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2009arXiv0909.2421P" } } }
