This leads to: (i) a way to classify of such integrals, based on the classification of certain embeddings of spherical varieties (whenever the latter is available), (ii) a conjecture which would imply a vast generalization of the method, and (iii) an explanation of the phenomenon of \"weight factors\" in a relative trace formula. We also prove results of independent interest, such as the generalized Cartan decomposition for spherical varieties of split groups over p-adic fields (following an argument of Gaitsgory and Nadler).", "revisions": [ { "version": "v3", "updated": "2013-08-04T10:15:23.000Z" } ], "analyses": { "subjects": [ "11F67" ], "keywords": [ "spherical varieties", "integral representations", "l-functions", "period integrals", "rankin-selberg integrals" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2009arXiv0905.4245S" } } }
