An Infinite Natural Product

open access: yesAnnales Mathematicae Silesianae, 2018
We study a countably infinite iteration of the natural product between ordinals.We present an “effective” way to compute this countable natural product; in the non trivial cases the result depends only on the natural sum of the degrees of the factors ...

Irrational Sums

open access: yesRocky Mountain Journal of Mathematics, 1995
Sufficient conditions for the irrationality of the sum of the series \(\sum_{n\geq 1} 1/H (f(n))\) are obtained. Here \(H(k)\) is a recurrent sequence and \(f\) is a strictly increasing function from the set of positive integers to the set of nonnegative integers. All the proofs are based on an elementary irrational criterion due to the reviewer [Glasg.

Bilinear sums of Gauss sums [PDF]

open access: yesActa Arithmetica, 2022
Let \(p \geq 3\) be a prime number. Motivated by results on bilinear sums of Kloosterman sums and their generalisations, the author considers sums with Gauss sums \[ G(m, n)=\sum_{x=1}^{p} \mathbf{e}_{p}\left(m x+n x^{2}\right), \] where \(\mathbf{e}_{p}(z)=\exp (2 \pi i z / p)\).
