The action is shown to be ergodic with respect to a natural measure. This measure is defined using the push-forward measure associated to a map defined by the presentation of the surface group. given by the pushforward of Haar measure. This result is an extension of earlier results of Goldman for orientable surfaces.", "revisions": [ { "version": "v3", "updated": "2009-01-27T10:09:22.000Z" } ], "analyses": { "subjects": [ "57M05", "22D40", "20F34" ], "keywords": [ "mapping class group", "moduli space", "non-orientable surface", "ergodic actions", "representations" ], "note": { "typesetting": "TeX", "pages": 41, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008arXiv0807.1615P" } } }
