摘要

f(z)=A(n)n(k1)/2e(nz)f(z) = \sum A(n) n^{(k-1)/2} e(nz)Γ0(N)\Gamma_0(N) 上权 k3k \geq 3、带特征 χ\chi 的尖形式。通过研究某个平移卷积和,我们证明了对 ϵ>0\epsilon>0nXA(n2+h)=cf,hX+Of,h,ϵ(X34+ϵ)\sum_{n \leq X} A(n^2+h) = c_{f,h} X + O_{f,h,\epsilon}(X^{\frac{3}{4}+\epsilon}),改进了 Blomer 于 2008 年误差为 X67+ϵX^{\frac{6}{7}+\epsilon} 的结果。本文包含一个由 Raphael S. Steiner 撰写的附录,证明了某些谱平均的更强界。
