Fibonacci Sums Modulo 5

open access: yesAnnales Mathematicae Silesianae
We develop closed form expressions for various finite binomial Fibonacci and Lucas sums depending on the modulo 5 nature of the upper summation limit. Our expressions are inferred from some trigonometric identities.

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.

On Mersenne Numbers and their Bihyperbolic Generalizations

open access: yesAnnales Mathematicae Silesianae
In this paper, we introduce Mersenne and Mersenne–Lucas bihyperbolic numbers, i.e. bihyperbolic numbers whose coefficients are consecutive Mersenne and Mersenne–Lucas numbers.

A Note on Generalized Hybrid Tribonacci Numbers

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2020
In this paper, we introduce the generalized hybrid Tribonacci numbers. These numbers can be considered as a generalization of the generalized complex Tribonacci, generalized hyperbolic Tribonacci and generalized dual Tribonacci numbers.

A new member of the Pell sequences: The pseudo-Pell sequence

open access: yes
In this study, we define a new family of the Pell numbers and establish some properties of the relation to the ordinary Pell numbers. We give some identities the pseudo-Pell numbers.

On a New One Parameter Generalization of Pell Numbers

open access: yesAnnales Mathematicae Silesianae, 2019
In this paper we present a new one parameter generalization of the classical Pell numbers. We investigate the generalized Binet’s formula, the generating function and some identities for r-Pell numbers.

More on finite sums that involve reciprocals of products of generalized Fibonacci numbers, Integers 14 (2014), #A4. Available at http://www.integers-ejcnt.org/vol14.html. 2010 Mathematics Subject Classification: Primary 11B39; Secondary 11B37. Keywords: r

open access: yes, 2020
In this paper we find closed forms for certain finite sums. In each case the denominator of the summand consists of products of generalized Fibonacci numbers.

A note on some Diophantine equations

open access: yes, 2017
Let k 3 be an odd integer. In this paper we investigate all positive integer solutions of the equations x4 kx2yCy2D A, x4 kx2yCy2D A.k2 4/; x4 .k2 4/y2D 4A; and x2 .k2 4/y4 D 4A with AD .k 2/: We show that if k 1.mod8/ and k2 4 be a square-free integer ...

On Diophantine equations involving Lucas sequences

open access: yesOpen Mathematics, 2019
In this paper, we shall study the Diophantine equation un = R(m)P(m)Q(m), where un is a Lucas sequence and R, P and Q are polynomials (under weak assumptions).
