On Averages of Exponential Sums over Primes

1987
In this paper we shall be concerned with obtaining approximations to and estimates for the sum $${{\text{S}}_{\text{N}}}(\alpha ){\text{ = }}\sum\limits_{{\text{n}} \leqslant {\text{N}}} {{\text{e}}({\text{n}}\alpha ) \wedge {\text{(n)}}}$$ where e(x) = exp(2πix), α is real, and Λ(n) is the von Mangoldt function.

The L ¹ mean of Exponential Sums over Primes

Bulletin of the London Mathematical Society, 1988
The author investigates the behaviour of the \(L^ 1\)-mean \(\int^{1}_{0}| S(x)| dx\) of the exponential sum \(S(x) = \sum_{n\leq X}\Lambda(n)e^{2\pi inx}\), where \(\Lambda\) is von Mangoldt's function. Such means often arise in investigations in analytic number theory.

Exponential sum estimates over subgroups and almost subgroups of $$ \mathbb{Z}_{Q}^{*} $$ , where Q is composite with few prime factors

GAFA Geometric And Functional Analysis, 2006
In this paper we extend the exponential sum results from [BK] and [BGK] for prime moduli to composite moduli q involving a bounded number of prime factors. In particular, we obtain nontrivial bounds on the exponential sums associated to multiplicative subgroups H of size qδ, for any given δ >  0.

Effective estimates of exponential sums over primes

1996
The asymptotic behavior of the sum $$S(x,\alpha ) = \sum\limits_{n \leqslant x} {\pi (n)e(n\alpha ),}$$ where α is real, e(α) = e2πiα, and Λ is the von Mangoldt function, has been extensively studied by many authors. It plays a central role in Vinogradov’s solution of the 3-primes conjecture [10].
