On b-concatenations of two k-generalized Fibonacci numbers
Let k≥2 be an integer. One of the generalization of the classical Fibonacci sequence is defined by the recurrence relation Fn(k)=Fn-1(k)+⋯+Fn-k(k) for all n≥2 with the initial values Fi(k)=0 for i=2-k,…,0 and F1(k)=1.Fn(k) is an order k generalization of the Fibonacci sequence and it is called k-generalized Fibonacci sequence or shortly k-Fibonacci sequence. Banks and Luca [7], among other things, determined all Fibonacci numbers which are concatenations of two Fibonacci numbers. In this paper, we consider the analogue of this problem in more general manner by taking into account the concatenations of two terms of the same sequence in base b≥2. First, we show that there exists only finitely many such concatenations for each k≥2 and b≥2. Next, we completely determine all these concatenations for all k≥2 and 2≤b≤10.

Growing patterns : Fibonacci numbers in nature
What's the biggest mathematical mystery in nature? Fibonacci numbers! The pattern creeps up in the most unexpected places. It's clear that math holds secrets to nature and that nature holds secret numbers.

Generalized Cassini identities via the generalized Fibonacci fundamental system. Applications
In this paper we explore the generalized Cassini identities for the weighted generalized Fibonacci sequences, through the associated generalized Fibonacci fundamental system. Some algebraic, combinatoric and analytic properties of these identities are established. Applications to generalized Fibonacci and Pell numbers are provided, and some special cases are studied.

Rabbits, rabbits everywhere : a Fibonacci tale
Rapidly multiplying rabbits are taking over the village of Chee, and soon there are so many that even the Pied Piper cannot get rid of them, but a girl named Amanda discovers a pattern that leads to a way to make the rabbits leave.

Novel Results for Two Generalized Classes of Fibonacci and Lucas Polynomials and Their Uses in the Reduction of Some Radicals
The goal of this study is to develop some new connection formulae between two generalized classes of Fibonacci and Lucas polynomials. Hypergeometric functions of the kind 2F1(z) are included in all connection coefficients for a specific z. Several new connection formulae between some famous polynomials, such as Fibonacci, Lucas, Pell, Fermat, Pell–Lucas, and Fermat–Lucas polynomials, are deduced as special cases of the derived connection formulae. Some of the introduced formulae generalize some of those existing in the literature. As two applications of the derived connection formulae, some new formulae linking some celebrated numbers are given and also some newly closed formulae of certain definite weighted integrals are deduced. Based on using the two generalized classes of Fibonacci and Lucas polynomials, some new reduction formulae of certain odd and even radicals are developed.

On Matrices with Bidimensional Fibonacci Numbers
In this paper, the bidimensional extensions of the Fibonacci numbers are explored, along with a detailed examination of their properties, characteristics, and some identities. We introduce and study the matrices with bidimensional Fibonacci numbers, focusing in particular on their recurrence relation, key properties, determinant, and various other identities. It is our purpose to study the matrix version of bidimensional Fibonacci numbers and provide new results and sometimes extensions of some results existing in the literature. We aim to introduce these matrices using the bidimensional Fibonacci numbers and to give the determinant of these matrices.
