设g(z)是SL(2,Z)的Maass尖点形式,λ g(n)是g(z)的n阶Fourier系数.本文研究等差数列上按Fourier系数扭曲的非线性指数和∑ n <$Xn <$l mod q λ g(n)e(α n β).证明了当β= 1/2,α接近± 2kq,k∈ Z+时的一个渐近公式.
Let g (z) be a Maass cusp form for SL (2, Z), and let λ g (n) be the n-th Fourier coefficient of g (z). In this paper we investigate the nonlinear exponential sum∑ n∼ X n≡ l mod q λ g (n) e (α n β) twisted by Fourier coefficient over the arithmetic progression. We prove an asymptotic formula when β= 1/2 and α is close to±2 k q, k∈ Z+.
