Perfect divisibility and 2‐divisibility

open access: yesJournal of Graph Theory, 2018
AbstractA graph G is said to be 2‐divisible if for all (nonempty) induced subgraphs H of G, can be partitioned into two sets such that and . (Here denotes the clique number of G, the number of vertices in a largest clique of G). A graph G is said to be perfectly divisible if for all induced subgraphs H of G, can be partitioned into two sets such ...

Number theory in secondary schools’ mathematics

open access: yesLietuvos Matematikos Rinkinys, 2021
Schools’ curricula are analyzed in terms of Number Theory.  We deduce,  that the concept of number is first and main in secondary schools’ Mathematics.  The problems of divisibility of numbers are also discussed, the examples of such problems are given.

On p-Adic Estimates of Weights in Abelian Codes over Galois Rings [PDF]

open access: yes, 2005
Let p be a prime. We prove various analogues and generalizations of McEliece's theorem on the p-divisibility of weights of words in cyclic codes over a finite field of characteristic p. Here we consider Abelian codes over various Galois rings.

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.

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.

SOME CONNECTIONS BETWEEN THE SMARANDACHE FUNCTION AND THE FIBONACCI SEQUENCE [PDF]

open access: yes, 2013
This paper is aimed to provide generalizations of the Smarandache function. They will be constructed by means of sequences more general than the sequence of the factorials.

Divisibility properties of random samples of integers

open access: yes, 2020
This paper is devoted to survey the rich theory, some of it quite recent, concerning the divisibility properties, of various kinds, of random r-tuples of positive ...

A product autoregressive model with log-Laplace marginal distribution

open access: yesStatistica, 2013
The log-Laplace distribution and its properties are considered. Some important properties like multiplicative infinite divisibility, geometric multiplicative infinite divisibility and self-decomposability are discussed.

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.
