We use Ichino's period formula combined with a relative trace formula to show exact averages of $L(3k-1,f\\times g\\times h)$. We also present some applications of the average formulas to the nonvanishing problem, giving a lower bound on the number of nonvanishing central $L$-values when one of the forms is fixed.", "revisions": [ { "version": "v1", "updated": "2021-01-29T04:30:34.000Z" } ], "analyses": { "subjects": [ "11F67", "11F72" ], "keywords": [ "central values", "triple product", "nonvanishing", "ichinos period formula", "hecke operators" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
