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…
