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.

Divisibility of Fibonomial coefficients in terms of their digital representations and applications

open access: yesAIMS Mathematics, 2022
We give a characterization for the integers $ n \geq 1 $ such that the Fibonomial coefficient $ {pn \choose n}_F $ is divisible by $ p $ for any prime $ p \neq 2, 5 $.

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_ ...

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.

Plastid division [PDF]

open access: yesAoB PLANTS, 2010
Plastids undergo a process of binary fission in order to replicate. Plastid replication is required at two distinct stages of plant growth: during cell division to ensure correct plastid segregation, and during cell expansion and development to generate large populations of functional plastids, as in leaf mesophyll cells.

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.
