Asymptotics for the Fourier coefficients of eta-quotients [PDF]
Journal of Number Theory, 2018 We study the asymptotics for the Fourier coefficients of a broad class of eta-quotients, $$\prod_{r=1}^R \left(\prod_{k\ge 1}\left(1-q^{m_r k}\right)\right)^{\delta_r},$$ where $m_1,\ldots,m_R$ are $R$ distinct positive integers and $\delta_1,\ldots ...

Records on the vanishing of Fourier coefficients of powers of the Dedekind eta function [PDF]
Research in Number Theory, 2018 In this paper we significantly extend Serre’s table on the vanishing properties of Fourier coefficients of odd powers of the Dedekind eta function. We address several conjectures of Cohen and Strömberg and give a partial answer to a question of Ono.

ANALYTIC FUNCTIONS OF INFINITE ORDER IN HALF-PLANE
Проблемы анализа, 2022 J. B. Meles (1979) considered entire functions with zeros restricted to a finite number of rays. In particular, it was proved that if 𝑓 is an entire function of infinite order with zeros restricted to a finite number of rays, then its lower order ...

Fourier coefficients of half-integral weight cusp forms and Waring’s problem [PDF]
The Ramanujan journal, 2017 Extending the approach of Iwaniec and Duke, we present strong uniform bounds for Fourier coefficients of half-integral weight cusp forms of level N. As an application, we consider a Waring-type problem with sums of mixed powers.
