摘要:

令$A_f(1,n)$为$GL(3)$ Maass尖点形式$f$的归一化傅立叶系数,令$a_g(n)$为$GL(2)$尖点形式$g$的归一化傅立叶系数。令$λ(n)$为$A_f(1,n)$或三重除数函数$d_3(n)$。本文证明了对任意$ε>0$,任意整数$r\geq 1$和$r^{5/2}X^{1/4+7δ/2}\leq H\leq X$都有$δ>0$,$$ \frac{1}{H}\sum_{h\geq 1}W\left(\frac{h}{H}\right) \sum_{n\geq 1}λ(n)a_g(rn+h)V\left(\frac{n}{X}\right)\ll X^{1-δ+ε}, $$,其中$V$和$W$是光滑紧支撑函数,隐含常数只依赖于相应的形式和$ε$ .

英文摘要:

Let $A_f(1,n)$ be the normalized Fourier coefficients of a $GL(3)$ Maass cusp form $f$ and let $a_g(n)$ be the normalized Fourier coefficients of a $GL(2)$ cusp form $g$. Let $λ(n)$ be either $A_f(1,n)$ or the triple divisor function $d_3(n)$. It is proved that for any $ε>0$, any integer $r\geq 1$ and $r^{5/2}X^{1/4+7δ/2}\leq H\leq X$ with $δ>0$, $$ \frac{1}{H}\sum_{h\geq 1}W\left(\frac{h}{H}\right) \sum_{n\geq 1}λ(n)a_g(rn+h)V\left(\frac{n}{X}\right)\ll X^{1-δ+ε}, $$ where $V$ and $W$ are smooth compactly supported functions, and the implied constants depend only on the associated forms and $ε$.
