Waring's problem in the natural numbers with binary expansions of a special type [PDF]

open access: yesarXiv, 2012
Let $\mathbb{N}_0$ be a class of natural numbers whose binary expansions contain even numbers of ones. Waring problem in numbers of class $\mathbb{N}_0$ is solved.

On the distance between perfect numbers [PDF]

open access: yesarXiv, 2012
It is shown that there exist infinitely many triangular numbers (congruent to 3 mod 12) which cannot be the distance between two perfect numbers.

Pell Numbers whose Euler Function is a Pell Number [PDF]

open access: yesarXiv, 2015
In this paper, we show that the only Pell numbers whose Euler function is also a Pell number are $1$ and $2$.

Enumerating number fields [PDF]

open access: yesarXiv, 2019
We construct small models of number fields and deduce a better bound for the number of number fields of given degree and bounded discriminant.

On q-deformed Stirling numbers [PDF]

open access: yesInternational Journal of Mathematics and Computations 17 (2) 2012, 2007
The purpose of this article is to introduce q-deformed Stirling numbers of the first and second kinds. Relations between these numbers, Riemann zeta function and q-Bernoulli numbers of higher order are given. Some relations related to the classical Stirling numbers and Bernoulli numbers of higher order are found.

Number of Compositions and Convolved Fibonacci numbers [PDF]

open access: yesarXiv, 2010
We consider two type of upper Hessenberg matrices which determinants are Fibonacci numbers. Calculating sums of principal minors of the fixed order of the first type leads us to convolved Fibonacci numbers. Some identities for these and for Fibonacci numbers are proved.

Bernoulli-Carlitz and Cauchy-Carlitz numbers with Stirling-Carlitz numbers [PDF]

open access: yesarXiv, 2017
Recently, the Cauchy-Carlitz number was defined as the counterpart of the Bernoulli-Carlitz number. Both numbers can be expressed explicitly in terms of so-called Stirling-Carlitz numbers. In this paper, we study the second analogue of Stirling-Carlitz numbers and give some general formulae, including Bernoulli and Cauchy numbers in formal power series

Investigation of Generalized Hybrid Fibonacci Numbers and Their Properties [PDF]

open access: yesarXiv, 2018
In \cite{Oz}, M. \"Ozdemir defined a new non-commutative number system called hybrid numbers. In this paper, we define the hybrid Fibonacci and Lucas numbers. This number system can be accepted as a generalization of the complex ($\textbf{i}^{2}=-1$), hyperbolic ($\textbf{h}^{2}=1$) and dual Fibonacci number ($\varepsilon^{2}=0$) systems.

A note on k-tridiagonal matrices with the balancing and Lucas-balancing numbers

open access: yes, 2015
In this note, we consider one type of k-tridiagonal matrix family whose permanents and determinants are specified to the balancing and Lucas-balancing numbers. Moreover, we provide some properties between Chebyshev polynomial properties and the given number sequences.
