On the Application of a Hybrid Incomplete Exponential Sum to Aperiodic Hamming Correlation of Some Frequency-Hopping Sequences [PDF]

open access: yesEntropy
Frequency-hopping sequences are essential in frequency-hopping spread spectrum communication systems due to their strong anti-interference capabilities, low probability of interception, and high confidentiality.

Goldbach partitions and norms of cusp forms

open access: yesJournal of Numerical Analysis and Approximation Theory, 2019
An integral formula for the Goldbach partitions requires uniform convergence of a complex exponential sum. The dependence of the coefficients of the series is found to be bounded by that of cusp forms.

High-dimensional Lehmer problem on Beatty sequences

open access: yesAIMS Mathematics, 2023
Let $ q $ be a positive integer. For each integer $ a $ with $ 1 \leqslant a < q $ and $ (a, q) = 1 $, it is clear that there exists one and only one $ \bar{a} $ with $ 1 \leqslant\bar{a} < q $ such that $ a \bar{a} \equiv 1(q) $.

On the exponential sums estimates related to Fourier coefficients of GL3 Hecke-Maaß forms

open access: yesAIMS Mathematics, 2023
Let $ F $ be a normlized Hecke-Maaß form for the congruent subgroup $ \Gamma_0(N) $ with trivial nebentypus. In this paper, we study the problem of the level aspect estimates for the exponential sum $ \mathscr{L}_F(\alpha) = \sum\limits_{n\le X} A_F(n,
