摘　　要：在解析数论领域,探讨全纯尖形式的傅里叶系数具有重要的理论价值.通过复变函数的积分技巧,结合自守L-函数的凸界以及积分均值估计方法,研究了不同序列上傅里叶系数的一致均值估计,形式化表达为∑n≤xλf nλf n j,j=2,3,其中f是全模群Γ=SL(2,Z)上权为偶数k的Hecke特征型,λf n是其在尖点∞处傅里叶展开的第n个标准化傅里叶系数.In the field of analytic number theory,exploring the Fourier coefficients of holomorphic modular form holds significant theoretical value.This paper will use the method of integration of complex variable functions,combing with the convexity bounds of the automorphic L-function and estimates of the mean value,studies the uniform mean estimates of Fourier coefficients on different sequences.The formal expression is as follows∑n≤xλf nλf n j,j=2,3,where f be a Hecke eigenform of even integral weights k for the full modular groupΓ=SL(2,Z)andλf n be the nth normalized Fourier coefficient of its Fourier expansion at the cusp∞.
