By a conjecture of Brumer-Murty, the rank should be equal to half of the dimension. Equivalently, almost all newforms of weight two and level $q$ have analytic rank $\\leq 1$. We show that either Landau-Siegel zeros do not exist, or that almost all such newforms have analytic rank $\\leq 2$. In particular, almost all odd newforms have analytic rank equal to one. Additionally, for a sparse set of primes $q$ we show the rank of $J_0(q)$ is asymptotically equal to the rank predicted by the Brumer-Murty conjecture.", "revisions": [ { "version": "v1", "updated": "2021-02-05T10:24:47.000Z" } ], "analyses": { "subjects": [ "11F41", "11F66", "11M20", "11F11" ], "keywords": [ "landau-siegel zeros", "automorphic l-functions", "analytic rank equal", "sparse set", "large primes" ], "note": { "typesetting": "TeX", "pages": 50, "language": "en", "license": "arXiv", "status": "editable" } } }
