This follows from the computation of new $\\mathrm{SL}_2$-period integrals associated with newforms $f$ and $g$ of even weight and odd squarefree level. The same computations also lead to a central value formula for degree $6$ complex $L$-series of the form $L(f \\otimes \\mathrm{Ad}(g), s)$, extending previous work in arXiv:1804.02352.", "revisions": [ { "version": "v1", "updated": "2020-01-09T19:06:58.000Z" } ], "analyses": { "subjects": [ "11F67", "11F37", "11F27" ], "keywords": [ "subconvexity problem", "automorphic", "odd squarefree level", "central value formula", "computation" ], "note": { "typesetting": "TeX", "pages": 34, "language": "en", "license": "arXiv", "status": "editable" } } }
