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…

Shifted convolution sums involving theta series

Qingfeng Sun

Let $f$ be a cuspidal newform (holomorphic or Maass) of arbitrary level and nebentypus and denote by $λ_{f} (n)$ its $n$ -th Hecke eigenvalue. Let $$ r(n)=\#\left\{(n_1,n_2)\in \mathbb…

Hybrid bounds for twists of $G L (3)$ $L$ -functions

Qingfeng Sun

Let $π$ be a Hecke-Maass cusp form for $S L (3, Z)$ and $χ = χ_{1} χ_{2}$ a Dirichlet character with $χ_{i}$ primitive modulo $M_{i}$ . Suppose that $M_{1}$ , $M_{2}$ are primes such that $\m…
