Ibragimov–Gadjiev operators based on q-integers [PDF]

open access: goldAdvances in Difference Equations, 2018
In this paper, we define the q-analogue of the generalized linear positive operators introduced by Ibragimov and Gadjiev in 1970. We study some approximation properties of these new operators, and we show that this sequence of operators is a ...

Statistics on Lattice Walks and q-Lassalle Numbers [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2015
This paper contains two results. First, I propose a $q$-generalization of a certain sequence of positive integers, related to Catalan numbers, introduced by Zeilberger, see Lassalle (2010).

On p/q-recognisable sets [PDF]

open access: yesLogical Methods in Computer Science, 2021
Let p/q be a rational number. Numeration in base p/q is defined by a function that evaluates each finite word over A_p={0,1,...,p-1} to some rational number. We let N_p/q denote the image of this evaluation function.

Split logarithm problem and a candidate for a post-quantum signature scheme [PDF]

open access: yesComputer Science Journal of Moldova, 2022
A new form of the hidden discrete logarithm problem, called split logarithm problem, is introduced as primitive of practical post-quantum digital signature schemes, which is characterized in using two non-permutable elements $A$ and $B$ of a finite non-

On units of some fields of the form $\mathbb{Q}\big(\sqrt2, \sqrt{p}, \sqrt{q}, \sqrt{-l}\big)$ [PDF]

open access: yesMathematica Bohemica, 2023
Let $p\equiv1\pmod8$ and $q\equiv3\pmod8$ be two prime integers and let $\ell\not\in\{-1, p, q\}$ be a positive odd square-free integer. Assuming that the fundamental unit of $\mathbb{Q}\big(\sqrt{2p}\big) $ has a negative norm, we investigate the unit ...

On the solutions of the equation p=x^2+y^2+1 in Lucas sequences

open access: yesWasit Journal for Pure Sciences, 2023
In 1970, Motohashi proved that there are an infinite number of primes having the form p=x^2+y^2+1 for some nonzero integers x and y. In this paper, we present a technique for studying the solutions of the equation p=x^2+y^2+1, where the unknowns are ...

Characterization of Upper Detour Monophonic Domination Number

open access: yesCubo, 2020
This paper introduces the concept of \textit{upper detour monophonic domination number} of a graph. For a connected graph $G$ with vertex set $V(G)$, a set $M\subseteq V(G)$ is called minimal detour monophonic dominating set, if no proper subset of $M ...

On distribution of the number of semisimple rings of order at most x in an arithmetic progression [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics, 2023
Let ℓ and q denote relatively prime positive integers. In this article, we derive the asymptotic formula for the summation Σ_{n≤x, n≡ℓ (mod q)} S(n), where S(n) denotes the number of non-isomorphic finite semisimple rings with n elements.

Resonance between the Representation Function and Exponential Functions over Arithemetic Progression

open access: yesJournal of Mathematics, 2021
Let rn denote the number of representations of a positive integer n as a sum of two squares, i.e., n=x12+x22, where x1 and x2 are integers. We study the behavior of the exponential sum twisted by rn over the arithmetic progressions ∑n∼Xn≡lmodqrneαnβ ...

A note on type 2 q-Bernoulli and type 2 q-Euler polynomials

open access: yesJournal of Inequalities and Applications, 2019
As is well known, power sums of consecutive nonnegative integers can be expressed in terms of Bernoulli polynomials. Also, it is well known that alternating power sums of consecutive nonnegative integers can be represented by Euler polynomials.
