摘要
设 f 和 g 分别是全模态群 Γ = SL(2, Z) 的偶数积分权重 k1 和 k2 的两个不同的原始全形尖顶形式。用 λf (n) 和 λg(n) 分别表示 f 和 g 的 n 次归一化傅里叶系数。在本文中,我们考虑求和函数 Xn=a2+b2≤xλf (n)iλg(n)j ,对于 x ≥ 2,其中 a、b∈ Z,i、j ≥ 1 为正整数。
ESTIMATE FOR HIGHER MOMENTS OF CUSP FORM COEFFICIENTS OVER SUM OF TWO SQUARES COEFFICIENTS OVER SUM OF TWO SQUARES
Let f and g be two distinct primitive holomorphic cusp forms of even integral
weights k1 and k2 for the full modular group Γ = SL(2, Z), respectively. Denote
by λf (n) and λg(n) the nth normalized Fourier coefficients of f and g,
respectively. In this paper, we consider the summatory function
X
n=a2+b2≤x
λf (n)iλg(n)j ,
for x ≥ 2, where a, b ∈ Z and i, j ≥ 1 are positive integers.
