On Some Exponential Sums [PDF]

open access: yesProceedings of the National Academy of Sciences, 1948
Verf. entwickelt den Zusammenhang zwischen zyklischen algebraischen Kongruenzfunktionen\-körpern einerseits und Charakter- bzw. Exponentialsummen andrerseits. Seiner einleitenden Bemerkung, daß er eine genaue Formulierung dieses Zusammenhangs in der Literatur nicht finden konnte, sei durch den Hinweis auf folgende Arbeiten begegnet: Ref. [J.

A note on exponential sums [PDF]

open access: yesPacific Journal of Mathematics, 1969
The paper begins with a few applications of Rédei's theorem on sums of the form \( B=\sum_{s=1}^{p-1} c_{\delta} \zeta^{s} \) where \( c_{s}= \pm 1 \) and \( \zeta \) is a primitive \( p \)-th root of unity. (See this Zbl. 29, 109.) For instance it is proved that \( |B|^{2} \equiv 0(\bmod p) \) if and only if \( B \) is a Gauss sum, i. e.

On Tractable Exponential Sums [PDF]

open access: yes, 2010
We consider the problem of evaluating certain exponential sums. These sums take the form $\sum_{x_1,...,x_n \in Z_N} e^{f(x_1,...,x_n) {2 πi / N}} $, where each x_i is summed over a ring Z_N, and f(x_1,...,x_n) is a multivariate polynomial with integer coefficients.

On the bivariate Padovan polynomials matrix [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics, 2023
In this paper, we intruduce the bivariate Padovan sequence we examine its various identities. We define the bivariate Padovan polynomials matrix. Then, we find the Binet formula, generating function and exponential generating function of the bivariate ...

The Distribution of Sum, Product and Ratio for the Absolutely Continuous Bivariate Generalized Exponential Random Variables [PDF]

open access: yesThe Egyptian Statistical Journal, 2017
Block and  Basu  bivariate  exponential  distribution is  a  standout  amongst the  most  absolutely continuous  bivariate   technique . This idea can  be  extended to the  generalized  exponential   technique  also.

ON HEILBRONN'S EXPONENTIAL SUM [PDF]

open access: yesThe Quarterly Journal of Mathematics, 2012
In the paper we prove a new upper bound for Heilbronn's exponential sum and obtain some applications of our result to distribution of Fermat quotients.

Efficient spectral estimation by MUSIC and ESPRIT with application to sparse FFT

open access: yesFrontiers in Applied Mathematics and Statistics, 2016
In spectral estimation, one has to determine all parameters of an exponential sum for finitely many (noisy)sampled data of this exponential sum.Frequently used methods for spectral estimation are MUSIC (MUltiple SIgnal Classification) and ESPRIT ...

Extended Wang sum and associated products.

open access: yesPLoS ONE, 2022
The Wang sum involving the exponential sums of Lerch's Zeta functions is extended to the finite sum of the Huwitz-Lerch Zeta function to derive sums and products involving cosine and tangent trigonometric functions.
