Exponential Sums with a Difference
Proceedings of the London Mathematical Society, 1990This paper extends work on exponential sums by \textit{E. Bombieri} and \textit{H. Iwaniec} [Ann. Sc. Norm. Super. Pisa Cl. Sci., IV.

Optimization with sums of exponentials and applications
2014 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2014We present a method for optimization with sums of exponentials subject to positivity constraints and apply it to the modeling of empirical probability distribution functions and to the design of IIR filters with non-negative impulse response. Our approach uses exponents in a sparse arithmetic progression and hence is able to transform the positivity ...

On the mean value of the mixed exponential sums with Dirichlet characters and general gauss sum [PDF]
Czechoslovak Mathematical Journal, 2013 summary:The main purpose of the paper is to study, using the analytic method and the property of the Ramanujan's sum, the computational problem of the mean value of the mixed exponential sums with Dirichlet characters and general Gauss sum. For integers $

The classical Kuzmin-Landau and van der Corput inequalities imply estimates for the exponential sum \(\sum_{a\leq n\leq b} e(f(n))\) once certain bounds for the derivatives \(f'(t)\) and \(f''(t)\) are known. These are generalized to double exponential sums \(\sum_{(n_1,n_2) \in D} e(f(n_1,n_2))\), where \(D\) is a rectangle, or a more general domain ...

Let \(p> 2\) be a prime and \(k\geq 2\), \(n\geq 2\). This paper concerns the exponential sum \[ \sum\limits^{p^n}_{x=1} e^{2\pi i (ax^k + bx) p^{-n}} \] where \(a, b\) are integers. This sum occurs in studies of Waring's problem. The author proves for this sum the bound \[ p^{(1-V)/2} p^{n/2} (b, p^n)^{1/2}\quad\text{for}\quad n\equiv 1\pmod k \] and ...

ON A CERTAIN GENERAL EXPONENTIAL SUM
International Journal of Number Theory, 2005In this paper we study the general exponential sum related to multiplicative functions f(n) with |f(n)| ≤ 1, namely we study the sum [Formula: see text] and obtain a non-trivial upper bound when α is a certain type of rational number.
