On $G L_{3}$ Fourier coefficients over values of mixed powers

Qingfeng Sun, Yanxue Yu

Let $A_{π} (n, 1)$ be the $(n, 1)$ -th Fourier coefficient of the Hecke-Maass cusp form $π$ for $S L_{3} (Z)$ and $ω (x)$ be a smooth compactly supported function. In this paper…

On some estimates involving Fourier coefficients of Maass cusp forms

Qingfeng Sun, Hui Wang

Let $f$ be a Hecke-Maass cusp form for $S L_{2} (Z)$ with Laplace eigenvalue $λ_{f} (Δ) = 1/4 + μ^{2}$ and let $λ_{f} (n)$ be its $n$ -th normalized Fourier coefficient. It is proved t…
