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}.

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.

On infinite divisibility of a class of two-dimensional vectors in the second Wiener chaos

open access: yesModern Stochastics: Theory and Applications, 2020
Infinite divisibility of a class of two-dimensional vectors with components in the second Wiener chaos is studied. Necessary and sufficient conditions for infinite divisibility are presented as well as more easily verifiable sufficient conditions.

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.

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.

Explicit formulas for the $p$-adic valuations of Fibonomial coefficients II

open access: yesAIMS Mathematics, 2020
In this article, we give explicit formulas for the $p$-adic valuations of the Fibonomial coefficients $\binom{p^a n}{n}_F$ for all primes $p$ and positive integers $a$ and $n$.

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.

On Two Problems Related to Divisibility Properties of z(n)

open access: yesMathematics, 2021
The order of appearance (in the Fibonacci sequence) function z:Z≥1→Z≥1 is an arithmetic function defined for a positive integer n as z(n)=min{k≥1:Fk≡0(modn)}. A topic of great interest is to study the Diophantine properties of this function. In 1992, Sun

Permutations preserving divisibility [PDF]

open access: yes, 2001
We give a proof of a theorem on the common divisibility of polynomials and permuted polynomials (over GF(2)) by a polynomial g(x)

Leibniz on Corporeal Substance [PDF]

open access: yesActa Baltica Historiae et Philosophiae Scientiarum, 2016
As an idealist, Gottfried Wilhelm Leibniz could not recognize anything corporeal as substantial. However, under the influence of Cartesian terminology, he devoted considerable effort to analysing the corporeal world, while not recognizing its real ...
