Exponential sums involving the divisor function over arithmetic progressions

open access: yesAIMS Mathematics, 2023
Let $ \phi(x) $ be a smooth function supported on $ [1, 2] $ with derivatives bounded by $ \phi^{(j)}(x)\ll 1 $ and $ d_3(n) $ be the number of ways to write $ n $ as a product of three factors. We get the asymptotic formula for the nonlinear exponential

Quasi-arithmetic means and OWA functions in interval-valued and Atanassov's intuitionistic fuzzy set theory [PDF]

open access: yes, 2011
In this paper we propose an extension of the well-known OWA functions introduced by Yager to interval-valued (IVFS) and Atanassov’s intuitionistic (AIFS) fuzzy set theory.

Arithmetic of positive characteristic L-series values in Tate algebras [PDF]

open access: yes, 2015
The second author has recently introduced a new class of L-series in the arithmetic theory of function fields over finite fields. We show that the value at one of these L-series encode arithmetic informations of certain Drinfeld modules defined over Tate

Sequences in finite fields yielding divisors of Mersenne, Fermat and Lehmer numbers, II [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
Let ρ be an odd prime ≥ 11. In Part I, starting from an M-cycle in a finite field 𝔽_ρ, we have established how the divisors of Mersenne, Fermat and Lehmer numbers arise.

Another generalization of the gcd-sum function [PDF]

open access: yes, 2013
We investigate an arithmetic function representing a generalization of the gcd-sum function, considered by Kurokawa and Ochiai in 2009 in connection with the multivariable global Igusa zeta function for a finite cyclic group.

Ray casting implicit fractal surfaces with reduced affine arithmetic [PDF]

open access: yes, 2007
A method is presented for ray casting implicit surfaces defined by fractal combinations of procedural noise functions. The method is robust and uses affine arithmetic to bound the variation of the implicit function along a ray.

Further Results on a Curious Arithmetic Function

open access: yesJournal of Mathematics, 2020
Let p be an odd prime number and n be a positive integer. Let vpn, N∗, and Q+ denote the p-adic valuation of the integer n, the set of positive integers, and the set of positive rational numbers, respectively.

Non‐interactive integrated membership authentication and group arithmetic computation output for 5G sensor networks

open access: yesIET Communications, 2021
Group‐oriented applications show its potential ability in the next generation of wireless sensor networks (5G WSNs), which have the particularity of being heterogeneous and so have different capabilities in terms of storage, computing, communicating and ...
