Padovan numbers that are concatenations of a Padovan number and a Perrin number

open access: yesPeriodica Mathematica Hungarica
The sequence of Padovan numbers defined by \(P_0 = P_1 = P_2 = 1; P_k = P_{k-2} + P_{k-3}\). The sequence of Perrin numbers defined by \(R_0 = 3, R_1 = 0, R_2 = 2; R_k = R_{k-2} + R_{k-3}\). The author determines all Padovan numbers which can be written as concatenations of a Padovan number and a Perrin number. Baker's method and Davenport reduction is

New Types of Distance Padovan Sequences via Decomposition Technique

open access: yesApplied Sciences (Switzerland), 2022
In this paper, we introduce new kinds of generalized Padovan sequences and study their properties using number decomposition techniques. In particular, we consider three types of generalized Padovan sequences defined by the same recurrence equation with ...

Generalized Padovan Numbers

open access: yesSymmetry
In this paper, we study a generalization of Padovan numbers. We define a generating function and matrix generators for the generalized Padovan sequence. Moreover, using graph methods and a special family of generalized Padovan sequences, we derive a multinomial formula for generalized Padovan numbers. We also prove some identities that generalize known

Padovan and Perrin Hybrid Number Identities

open access: yesCommunications in Advanced Mathematical Sciences, 2021
This work investigates the numbers of Padovan and Perrin hybrids. At first, the hybrid numbers, the sequences in the hybrid form, and their matrix forms are ordered as studied sequences. Thus, it was possible to display the negative index hybrids, define

On Gaussian Jacobsthal-Padovan Numbers

open access: yesCumhuriyet Science Journal, 2022
Gaussian Jacobsthal-Padovan numbers have been the central focus of this paper and firstly this number sequence has defined. Later, we have given the proof of the generating function of the Gaussian Jacobsthal-Padovan sequence.

The Hybrid Numbers of Padovan and Some Identities

open access: yesAnnales Mathematicae Silesianae, 2020
In this article, we will define Padovan’s hybrid numbers, based on the new noncommutative numbering system studied by Özdemir ([7]). Such a system that is a set involving complex, hyperbolic and dual numbers.

Repdigits as sums of three Padovan numbers [PDF]

open access: yesBoletin De La Sociedad Matematica Mexicana, 2019
AbstractLet $$ \{P_{n}\}_{n\ge 0} $${Pn}n≥0 be the sequence of Padovan numbers defined by $$ P_0=0 $$P0=0, $$ P_1 =1=P_2$$P1=1=P2, and $$ P_{n+3}= P_{n+1} +P_n$$Pn+3=Pn+1+Pn for all $$ n\ge 0 $$n≥0. In this paper, we find all repdigits in base 10 which can be written as a sum of three Padovan numbers.

Some New Graph Interpretations of Padovan Numbers

open access: yesSymmetry
Padovan numbers and Perrin numbers belong to the family of numbers of the Fibonacci type and they are well described in the literature. In this paper, by studying independent (1,2)-dominating sets in paths and cycles, we obtain new binomial formulas for Padovan and Perrin numbers.

The Extension of Added Sugar Use in Packaged Foods Targeted at Children in Brazil. [PDF]

open access: yesMatern Child Nutr
ABSTRACT Excessive added sugars intake in early childhood has been associated with an increased risk of obesity and other non‐communicable diseases. In Brazil, packaged foods form a substantial part of children's diets, yet no studies have examined the presence of added sugars in products specifically marketed to this population.

Some geometric properties of the Padovan vectors in Euclidean 3-space [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics, 2023
Padovan numbers were defined by Stewart (1996) in honor of the modern architect Richard Padovan (1935) and were first discovered in 1924 by Gerard Cordonnier.
