The Proof of a Conjecture on the Density of Sets Related to Divisibility Properties of z(n)

open access: yesMathematics, 2021
Let (Fn)n be the sequence of Fibonacci numbers. The order of appearance (in the Fibonacci sequence) of a positive integer n is defined as z(n)=min{k≥1:n∣Fk}.

Divisibility among determinants of power matrices associated with integer-valued arithmetic functions

open access: yesAIMS Mathematics, 2020
Let $a, b$ and $n$ be positive integers and $S = \left\{ {x_1, ..., x_n} \right\}$ be a set of $n$ distinct positive integers. The set $S$ is called a divisor chain if there is a permutation $\sigma $ of $\{1, ..., n\}$ such that $x_{\sigma (1)}|...|x_ ...

One more time about the relation between morphemic analysis and word-formation analysis [PDF]

open access: yesJužnoslovenski Filolog, 2019
One of the basic criteria when it comes to describing the surface structure of the derivative lexical units is distinguishing morphemic and word-formation analysis.

Linear divisibility sequences and Salem numbers [PDF]

open access: yes, 2017
We study linear divisibility sequences of order 4, providing a characterization by means of their characteristic polynomials and finding their factorization as a product of linear divisibility sequences of order 2.

Evolution Equations for Quantum Semi-Markov Dynamics

open access: yesEntropy, 2020
Using a newly introduced connection between the local and non-local description of open quantum system dynamics, we investigate the relationship between these two characterisations in the case of quantum semi-Markov processes.

DIVISIBILITY TESTS FOR SMARANDACHE SEMIGROUPS [PDF]

open access: yes, 2002
Two Divisibility Tests for Smarandache semigroups are given. Further, the notion of divisibility of elements in a semigroup is applied to characterize the Smarandache semigroups.

On the 2-adic order of Stirling numbers of the second kind and their differences [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2009
Let $n$ and $k$ be positive integers, $d(k)$ and $\nu_2(k)$ denote the number of ones in the binary representation of $k$ and the highest power of two dividing $k$, respectively.

Time: Avicenna, Aristotle; Two Perspectives or One? [PDF]

open access: yesحکمت و فلسفه, 2012
The concept of time, its existence, ontology, and epistemology are considered as a pivotal philosophical issue from the ancient Greek time up to now. Aristotle explicitly deals with this subject. His notion of time can be also seen in Avicenna’s writings.

New results on the divisibility of power GCD and power LCM matrices

open access: yesAIMS Mathematics, 2022
Let $ a, b $ and $ n $ be positive integers and let $ S $ be a set consisting of $ n $ distinct positive integers $ x_1, ..., x_{n-1} $ and $ x_n $. Let $ (S^a) $ (resp. $ [S^a] $) denote the $ n\times n $ matrix having $ \gcd(x_i, x_j)^a $ (resp. $ {\rm

Arithmetical Functions Associated with the k-ary Divisors of an Integer

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2018
The k-ary divisibility relations are a class of recursively defined relations beginning with standard divisibility and culminating in the so-called infinitary divisibility relation.
