Sums of the triple divisor function over values of a ternary quadratic form

Qingfeng Sun, Deyu Zhang

Let $τ_{3} (n)$ be the triple divisor function which is the number of solutions of the equation $d_{1} d_{2} d_{3} = n$ in natural numbers. It is shown that $$ \sum_{1\leq n_1,n_2,n_3\leq \sqrt…

Shifted convolution sums of $G L_{3}$ cusp forms with $θ$ -series

Qingfeng Sun

Let $A_{f} (1, n)$ be the normalized Fourier coefficients of a Hecke-Maass cusp form $f$ for $S L_{3} (Z)$ and $$ r_3(n)=\#\left\{(n_1,n_2,n_3)\in \mathbb{Z}^3:n_1^2+n_2^2+n_3^2=n…
