摘要: 设λf(n)是标准化的Hecke算子Tn的尖形式的傅立叶系数, σ(n)是除数和函数, φ(n)是欧拉函数。 利用解析的方法研究混合数论函数λf(n)σb(n)φc(n)的平均阶估计, 得到了上界估计∑n≤xλf(n)σb(n)φc(n)≪xb+c+1/2+ε,这里ε>0是任意的。

关键词: 数论函数, 自守L-函数, 全纯尖形式, 傅立叶系数

Abstract: Let λf(n) be the Fourier coefficients of cusp forms of the normalized Hecke operator Tn, σ(n) be the sum-of-divisors function, and φ(n) be the Eulers function. The average order estimation of hybrid arithmetic functions of the form λf(n)σb(n)φc(n) is investigated by using analytic methods, and the upper bound estimate ∑n≤xλf(n)σb(n)φc(n)≪xb+c+1/2+ε,for any ε>0 is obtained.

Key words: holomorphic cusp form, Fourier coefficients, automorphic L-function, arithmetic function
