Bounds for $G L_{2} \times G L_{2}$ $L$ -functions in depth aspect

Qingfeng Sun

Let $f$ and $g$ be holomorphic or Maass cusp forms for $S L_{2} (Z)$ and let $χ$ be a primitive Dirichlet character of prime power conductor $q = p^{κ}$ with $p$ pr…

A Bessel $δ$ -method and hybrid bounds for $GL_{2}$

Yilan Fan, Qingfeng Sun

Let $g$ be a primitive holomorphic or Maass newform for $Γ_{0} (D)$ . In this paper, by studying the Bessel integrals associated to $g$ , we prove an asymptotic Bessel $δ$ -identity asso…

A subconvex bound for twisted $L$ -functions

Qingfeng Sun, Hui Wang

Let $q > 2$ be a prime number, $χ$ a primitive Dirichlet character modulo $q$ and $f$ a primitive holomorphic cusp form or a Hecke-Maass cusp form of level $\ma…
