On the higher moments of the error term in the Rankin-Selberg problem

Jing Huang, Yoshio Tanigawa, Wenguang Zhai +1

Let $Δ_{1} (x; φ)$ denote the error term in the classical Rankin-Selberg problem. In this paper, we consider the higher power moments of $Δ_{1} (x; φ)$ and derive the asymptotic formulas f…

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…
