Automorphic spectra and the conformal bootstrap

P Kravchuk, D Mazáč, S Pal - Communications of the American …, 2024 - ams.org
We describe a new method for constraining Laplacian spectra of hyperbolic surfaces and 2-
orbifolds. The main ingredient is consistency of the spectral decomposition of integrals of …

Spectral Bounds on Hyperbolic 3-Manifolds: Associativity and the Trace Formula

J Bonifacio, D Mazac, S Pal - arXiv preprint arXiv:2308.11174, 2023 - arxiv.org
We constrain the low-energy spectra of Laplace operators on closed hyperbolic manifolds
and orbifolds in three dimensions, including the standard Laplace-Beltrami operator on …

Effective computation of Maass cusp forms

AR Booker, A Strömbergsson… - International …, 2006 - academic.oup.com
We study theoretical and practical aspects of high-precision computation of Maass forms.
First, we compute to over 1000 decimal places the Laplacian and Hecke eigenvalues for the …

Artin's conjecture, Turing's method, and the Riemann hypothesis

AR Booker - Experimental Mathematics, 2006 - Taylor & Francis
We present a group-theoretic criterion under which one may verify the Artin conjecture for
some (nonmonomial) Galois representations, up to finite height in the complex plane. In …

The Seiberg-Witten equations and the length spectrum of hyperbolic three-manifolds

F Lin, M Lipnowski - Journal of the American Mathematical Society, 2022 - ams.org
We exhibit the first examples of hyperbolic three-manifolds for which the Seiberg-Witten
equations do not admit any irreducible solution. Our approach relies on hyperbolic geometry …

Kloosterman sums and Maass cusp forms of half integral weight for the modular group

S Ahlgren, N Andersen - International Mathematics Research …, 2018 - academic.oup.com
We estimate the sums∑ c≤ x S (m, n, c, χ) c, where the are Kloosterman sums associated
with a multiplier system of half-integral weight on the modular group. Our estimates are …

[HTML][HTML] Algebraic and transcendental formulas for the smallest parts function

S Ahlgren, N Andersen - Advances in Mathematics, 2016 - Elsevier
Building on work of Hardy and Ramanujan, Rademacher proved a well-known formula for
the values of the ordinary partition function p (n). More recently, Bruinier and Ono obtained …

Properties of eigenvalues on Riemann surfaces with large symmetry groups

J Cook - arXiv preprint arXiv:2108.11825, 2021 - arxiv.org
On compact Riemann surfaces, the Laplacian has a discrete, non-negative spectrum of
eigenvalues of finite multiplicity. The spectrum is intrinsically linked to the geometry of the …

Twist‐minimal trace formulas and the Selberg eigenvalue conjecture

AR Booker, M Lee… - Journal of the London …, 2020 - Wiley Online Library
We derive a fully explicit version of the Selberg trace formula for twist‐minimal Maass forms
of weight 0 and arbitrary conductor and nebentypus character, and apply it to prove two …
