Additionally, we investigate various identities associated with these polynomials.

Fibonacci-based generalizations of degenerate Stirling numbers

Dişkaya, Orhan

This paper introduces and systematically investigates Fibonacci-based analogues and generalizations of degenerate Stirling and Lah numbers. We begin by recalling the classical definitions and key properties of Stirling numbers of both kinds, Lah numbers, Fibonacci numbers, and Fibonomial coefficients, along with F-falling and F-rising factorials. The foundational concept of degenerate numbers and their associated degenerate factorials, as initiated by Carlitz, is also reviewed. Our primary contribution is the definition of four new families of numbers: the degenerate F-Stirling numbers of the first kind and S1,λF(n,k), the degenerate F-Stirling numbers of the second kind S2,λF(n,k), and the degenerate F-Lah number LλF(n,k). These numbers are precisely characterized as connection coefficients between the standard power basis {xn:n≥0} and the F-falling and F-rising factorial bases, and their degenerate counterparts. We derive fundamental recurrence relations for each class of these new numbers, providing a structural foundation for their analysis. Furthermore, we establish their generating functions and prove several combinatorial identities, including inverse relations. Our methodology primarily utilizes generating function techniques and properties of degenerate Fibonacci-based...

On the Quaternion Padovan Numbers

Dişkaya, Orhan | Menken, Hamza

In the present work, we explore the concept of quaternion Padovan sequences, extending the classical Padovan sequence into the realm of quaternions. Quaternions, introduced by Hamilton in 1843, are a number system that generalizes complex numbers into four dimensions, with applications in various fields such as quantum physics, computer graphics, and three-dimensional rotations. The study begins by reviewing the definition and properties of quaternions, including their non- commutative multiplication rules and the formulation of quaternion numbers. The Padovan sequence is defined by the recurrence relation Pn+3 = Pn+1 + Pn with initial conditions P0 = P1 = P2 =1. This sequence is generalized to quaternions by defining quaternion Padovan numbers, denoted QP (a,b, c, d) , which follow a similar recurrence relation for each coordinate of the quaternion. The study provides detailed recurrence relations and initial conditions for these quaternion Padovan numbers and derives several new identities and plastic-like ratio. Furthermore, the study introduces the concept of quaternion Padovan sequences in four dimensions and investigates their algebraic properties, including the calculation of the norm and conjugate of these quaternion sequences.

PADOVAN AND PERRIN SPINORS

Dişkaya, Orhan | Menken, Hamza

Spinors are components of a complex vector space that can be re- lated to Euclidean space in both geometry and physics. In essence, the forms of usage include quaternions that are equivalent to Pauli spin matrices, which may be produced by thinking of a quaternion matrix as the compound. This study’s objective is the spinor structure that forms based on the quaternion al- gebra. In this work, first, spinors have been mathematically presented. Then, Padovan and Perrin spinors have been defined using the Padovan and Perrin quaternions. Later, we defined the algebraic structure for these spinors. Fi- nally, we have established certain identities such as the Binet formulas and generating functions for Padovan and Perrin spinors.

A NEW GENERALIZATION OF THE PADOVAN SEQUENCE

Dişkaya, Orhan | Menken, Hamza

Integers number sequences in mathematics are one of the subjects with the most ap- plication area. The Fibonacci number sequence has applications in many branches of science such as nature, anatomy, botany, zoology, art, music, analysis, physics, astronomy, chemistry, biology and computers. Since the positive real root of the Fibonacci number sequence gives the golden ratio, it has many applications. Many scientists deal with Fibonacci sequence and its generalizations in recent years. Some of these generalizations are number sequences such as Lucas, Pell, and Jacobthal [4, 5, 6]. In this study, the Padovan numbers sequence, which has a third-order characteristic equation, and some of its generalizations are examined. The Padovan sequence {Pn} is defined by the third order recurrence Pn+3 = Pn+1 + Pn with the initial conditions P0 = 1, P1 = 0 and P2 = 1. Feinberg [2] defined Tribonacci numbers. Hoggatt and Bicknell [3] gave Tribonacci poliynomials. Vieira and Alves [9] expressed Sequences of Tridovan and their iden- tities. The Tridovan sequence {T Pn} is defined by the forth order recurrence T Pn+4 = T Pn+2 + T Pn+1 + T Pn with the initial conditions T P−1 = 0, T P0 = 1, T P1 = 0 and T P2 = 1. G. P. Dresden and Z.

A New Encryption Algorithm Based on Fibonacci Polynomials and Matrices

Dişkaya, Orhan | Avaroğlu, Erdinç | Menken, Hamza

Confusion and diffusion features are two fundamental needs of encoded text or images. These features have been used in various encryption algorithms such as Advanced Encryption Standard (AES) and Data Encryption Standard (DES). The AES adopts the S- box table formed with irreducible polynomials, while the DES employs the Feistel and S- box structures. This study proposes a new encryption algorithm based on Fibonacci polynomials and matrices, which meets the fundamental needs of image encryption and provides an alternative to other encryption algorithms. The success of the proposed method was tested on three different images, as evidenced by the histogram analysis results of the sample images, together with the number of changing pixel rate (NPCR) and the unified averaged changed intensity (UACI). In addition, the root mean squared error (RMSE) suggests that the decoded images are consistent with the original images. It can therefore be summarized that the proposed encryption algorithm is suitable for image encryption.

COMPOSITIONS OF POSITIVE INTEGERS AND THE PADOVAN NUMBERS

Dişkaya, Orhan | Menken, Hamza

The Padovan sequence {Pn}n≥0 is defined by the third order recurrence (1) Pn+3 = Pn+1 + Pn with the initial conditions P0 = 1, P1 = 0 and P2 = 1. The Padovan sequence appears as sequence A000931 on the On-Line Encyclopedia of Integer Sequences (OEIS) [1]. For relevance, we consider as P−2 = P−1 = 0. In [2] the Padovan polynomial sequence {Pn(x)}n≥0 is defined by a third order recurrence (2) Pn+3(x) = xPn+1(x) + Pn(x) with the initial conditions P0(x) = 1, P1(x) = 0 and P2(x) = x. For relevance, we consider as P−2(x) = P−1(x) = 0. To simplify notation, take Pn(x) = Pn. A composition of an integer n is a representation of n as a sum of positive integers, for example the eight compositions of 4 are as follows: 4, 3+1, 1+3, 2+2, 2+1+1, 1 + 2 + 1, 1 + 1 + 2, 1 + 1 + 1 + 1. A partition of n is a representation of n as a sum of positive integers where the order of the summands is considered irrelevant[5]. A composition of a positive integer n is an ordered sum of 1s and 2s [3, 4]. For example, 2 has two distinct such compositions, and 3 has three, and 4 has five. In the present work, we study compositions of positive integers with 2s and 3s. We prove that these compositions can be given in terms of Padovan numbers. We create some flooring models of these compositions rela...

SOME NOTES ON THE PLASTIC CONSTANT

Dişkaya, Orhan | Menken, Hamza

The Padovan sequence is named after Richard Padovan who attributed its dis- covery to Dutch architect Hans van der Laan in his 1994 essay Dom. The Padovan sequence {Pn}n≥0 is defined by (1) P0 = P1 = P2 = 1 and Pn+3 = Pn+1 + Pn for all n ≥ 0. Here, Pn is the nth Padovan number. First few terms of this sequence are 1, 1, 1, 2, 2, 3, 4, 5, 7, 9, 12, 16, 21. The ratio of successive the Padovan number converges to the plastic constant. As n gets larger, it appers that PPn+1 n approaches a limit, namely, 1, 32471795724474602596 . . . The plastic number p (also known as the plastic constant, the plastic ratio, the platin number and the minimal Pisot number) is a mathematical constant which is the unique real solution of the cubic equation x3 − x − 1 = 0. It has the exact value p = s3 9 + √ 69 18 + s3 9 − √ 69 18 that was firstly defined in 1924 by Gerard Cordonnier. He described applications to architecture and illustrated the use of the plastic constant in many buildings (for the details see [1, 2, 3]). Its decimal expansion begins with α ≈ 1.3247 = p = P lastic ratio. In the present work we construct the plastic number in three-dimensional space. We examine the nested radicals and continued fraction expansions of the plastic ratio. Also, ...
