Generalized Fibonacci Numbers and Blackwell's Renewal Theorem [PDF]

open access: yes, 2010
We investigate a connection between generalized Fibonacci numbers and renewal theory for stochastic processes. Using Blackwell's renewal theorem we find an approximation to the generalized Fibonacci numbers. With the help of error estimates in the renewal theorem we figure out an explicit representation.

On a problem of Pillai with k-generalized Fibonacci numbers and powers of 2

open access: yes, 2018
For an integer $ k\geq 2 $, let $ \{F^{(k)}_{n} \}_{n\geq 0}$ be the $ k$--generalized Fibonacci sequence which starts with $ 0, \ldots, 0, 1 $ ($ k $ terms) and each term afterwards is the sum of the $k$ preceding terms.

Some properties of Fibonacci numbers, Fibonacci octonions and generalized Fibonacci-Lucas octonions [PDF]

open access: yesarXiv, 2015
In this paper we determine some properties of Fibonacci octonions. Also, we introduce the generalized Fibonacci-Lucas octonions and we investigate some properties of these elements.

Integrative Analysis of Diphasiastrum digitatum Holub: Unveiling Genetic Variation and Ecological Adaptations for Sustainable Ecosystem Management

open access: yesEcology and Evolution, Volume 15, Issue 3, March 2025.
We convergently derived the evolutionary scenario for a basal lycopod species, Diphasiastrum digitatum, from genotyping data and ecological modeling. This information can better inform decisions about conservation efforts for this and related valuable lycopods. ABSTRACT Understanding the diversity and ecological evolutionary history of plant species is

Fibonacci Numbers which are Products of two Pell Numbers [PDF]

open access: yesThe Fibonacci Quarterly, 2016, 2017
In this paper, we find all Fibonacci numbers which are products of two Pell numbers and all Pell numbers which are products of two Fibonacci numbers.

On the Enumeration and Asymptotic Analysis of Fibonacci Compositions [PDF]

open access: yesarXiv, 2021
We study Fibonacci compositions, which are compositions of natural numbers that only use Fibonacci numbers, in two different contexts. We first prove inequalities comparing the number of Fibonacci compositions to regular compositions where summands have a maximum possible value.

Behind phyllotaxis, within the meristem: a REM‐ARF complex shapes inflorescence in Arabidopsis thaliana

open access: yesThe Plant Journal, Volume 121, Issue 5, March 2025.
Significance Statement We showed that REM34 and REM35, cooperating with ARF7 and ARF19, regulate phyllotaxis establishment in Arabidopsis by the transcriptional control of a common set of genes and by influencing the cell cycle. This fundamental research study adds knowledge on the complex programs that drive inflorescence development, such as cell ...

A classification of infinite staircases for Hirzebruch surfaces

open access: yesJournal of Topology, Volume 18, Issue 1, March 2025.
Abstract The ellipsoid embedding function of a symplectic manifold gives the smallest amount by which the symplectic form must be scaled in order for a standard ellipsoid of the given eccentricity to embed symplectically into the manifold. It was first computed for the standard four‐ball (or equivalently, the complex projective plane) by McDuff and ...

Another type of generalized fibonacci series

open access: yesSemina: Ciências Exatas e Tecnológicas, 2004
The Fibonacci sequence, with many applications and occurrences in nature and arts is discussed in the present work. It is considered a generalization of the Fibonacci series by the introduction of a real coefficient in the recurrence relation.

Fibonacci and Telephone Numbers in Extremal Trees

open access: yesDiscussiones Mathematicae Graph Theory, 2018
In this paper we shall show applications of the Fibonacci numbers in edge-coloured trees. In particular we determine the successive extremal graphs in the class of trees with respect to the number of (A, 2B)-edge colourings.
