The Ratios Conjecture and upper bounds for negative moments of 𝐿-functions over function fields

H Bui, A Florea, J Keating - Transactions of the American Mathematical …, 2023 - ams.org
We prove special cases of the Ratios Conjecture for the family of quadratic Dirichlet $ L $-
functions over function fields. More specifically, we study the average of $ L (1/2+\alpha,\chi …

Nonvanishing for cubic L-functions

C David, A Florea, M Lalin - Forum of Mathematics, Sigma, 2021 - cambridge.org
We prove that there is a positive proportion of L-functions associated to cubic characters
over as well as into the number-field case (assuming the generalised Riemann hypothesis) …

Negative Moments of L–Functions With Small Shifts Over Function Fields

A Florea - International Mathematics Research Notices, 2024 - academic.oup.com
We consider negative moments of quadratic Dirichlet–functions over function fields.
Summing over monic square-free polynomials of degree in, we obtain an asymptotic formula …

Weighted central limit theorems for central values of -functions

HM Bui, N Evans, S Lester, K Pratt - Journal of the European …, 2024 - ems.press
We establish a central limit theorem for the central values of Dirichlet L-functions with
respect to a weighted measure on the set of primitive characters modulo q as q! 1. Under the …

On fundamental Fourier coefficients of Siegel cusp forms of degree 2

J Jääsaari, S Lester, A Saha - Journal of the Institute of Mathematics …, 2023 - cambridge.org
Let F be a Siegel cusp form of degree, even weight, and odd square-free level N. We
undertake a detailed study of the analytic properties of Fourier coefficients of F at …

Bounds for moments of cubic and quartic Dirichlet L-functions

P Gao, L Zhao - Indagationes Mathematicae, 2022 - Elsevier
We study the 2 k-th moment of central values of the family of primitive cubic and quartic
Dirichlet L-functions. We establish sharp lower bounds for all real k≥ 1/2 unconditionally for …

Large Fourier coefficients of half-integer weight modular forms

S Gun, W Kohnen, K Soundararajan - arXiv preprint arXiv:2004.14450, 2020 - arxiv.org
This article is concerned with the Fourier coefficients of cusp forms (not necessarily
eigenforms) of half-integer weight lying in the plus space. We give a soft proof that there are …

Distribution of toric periods of modular forms on definite quaternion algebras

M Suzuki, S Wakatsuki, S Yokoyama - Research in Number Theory, 2022 - Springer
Let D be a definite quaternion algebra over Q and O an Eichler order in D of square-free
level. We study distribution of the toric periods of algebraic modular forms of level O. We …
