Abstract

Let f be a normalized Hecke eigenform of weight k for the full modular group SL2(). In this paper, we obtain the asymptotic of higher moments of general divisor functions associated to the Fourier coefficients of Rankin–Selberg L-functions R(s,f×f), supported at the integers represented by primitive integral positive-definite binary quadratic forms (reduced forms) of a fixed discriminant D<0. We improve previous results in the case when the reduced form is given by 𝒬(x1,x2)=x12+x22.

稀疏集合中整数处 L 函数乘积的傅立叶系数振荡
设 f 是全模态群 SL2(ℤ) 权重为 k 的归一化赫克特征形式。在本文中,我们得到了与 Rankin-Selberg L 函数 R(s,f×f) 的傅里叶系数相关的一般除数函数的高阶矩的渐近值,R(s,f×f) 在整数处由固定判别式 D<0 的原始积分正定二元二次方程形式(还原形式)表示。当还原形式为𝒬(x1,x2)=x12+x22 时,我们改进了以前的结果。
