Decomposition of terms in Lucas sequences

open access: yesJournal of Logic and Analysis, 2009
Let N be any large integer. Proceeding directly to the factorization of N is not an easy task, even unfeasible unless N belongs to a particular family of integers. Then to surmount this major difficulty we might choose to ask about the factorization of an integer in a small neighborhood of N instead of N .

Pseudorandom generators based on Lucas Sequences

open access: yesRatio Mathematica, 1993
Pseudo-random sequence generators are the heart of Stream-cipher systems. This work presents some design criteria for such generators. based on innovative methods. To this aim the Lucas Sequences, reduced modulo a prime p.

ON THE SEQUENCES RELATED TO FIBONACCI AND LUCAS NUMBERS [PDF]

open access: yesJournal of the Korean Mathematical Society, 2005
The sequences \(\{U_n\}_{n\geq 0}\) and \(\{V_n\}_{n\geq 0}\) are introduced by recurrence relations: \[ \begin{aligned} U_n &= (q- 2)(U_{n-2}- U_{n-4},\;n\geq 4,\\ V_n &= (q-2) V_{n-2}- V_{n-4},\;n\geq 4\end{aligned} \] with initial conditions \(U_0= 0\), \(U_1= 1\), \(U_2= 1\), \(U_4= q- 1\), \(V_0= 2\), \(V_1= 1\), \(V_2= q-1\), where \(q\geq 5\) is

The relations between bi-periodic jacobsthal and bi-periodic jacobsthal lucas sequence

open access: yesCumhuriyet Science Journal, 2021
In this paper, one of the special integer sequences, Jacobsthal and Jacobsthal Lucas sequences which are encountered in computer science is generalized according to parity of the index of the entries of the sequences, called bi-periodic Jacobsthal and ...

Pseudoprimality related to the generalized Lucas sequences [PDF]

open access: yes, 2021
Some arithmetic properties and new pseudoprimality results concerning generalized Lucas sequences are presented. The findings are connected to the classical Fibonacci, Lucas, Pell, and Pell–Lucas pseudoprimality.

On some links between the generalised Lucas pseudoprimes of level k

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2023
Pseudoprimes are composite integers sharing behaviours of the prime numbers, often used in practical applications like public-key cryptography. Many pseudoprimality notions known in the literature are defined by recurrent sequences.

On Horadam-Lucas Sequence

open access: yesJournal of the Indonesian Mathematical Society, 2023
Horadam introduced a generalized sequence of numbers, describing its key features and the special sub-sequences obtained from specific choices of initial parameters. This sequence and its sub-sequences are known as the Horadam, generalized Fibonacci, and generalized Lucas numbers, respectively.

On properties of generalized Tridovan numbers [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics, 2023
In this paper, we examine generalized Tridovan sequences and treat in detail two cases called Tridovan sequences and Tridovan–Lucas sequences. We present Binet's formulas, generating functions, Simson formulas, and the summation formulas for these ...

On Generalized Jacobsthal and Jacobsthal–Lucas Numbers

open access: yesAnnales Mathematicae Silesianae, 2022
Jacobsthal numbers and Jacobsthal–Lucas numbers are some of the most studied special integer sequences related to the Fibonacci numbers. In this study, we introduce one parameter generalizations of Jacobsthal numbers and Jacobsthal–Lucas numbers.

A Note on Two Fundamental Recursive Sequences

open access: yesAnnales Mathematicae Silesianae, 2021
In this note, we establish some general results for two fundamental recursive sequences that are the basis of many well-known recursive sequences, as the Fibonacci sequence, Lucas sequence, Pell sequence, Pell-Lucas sequence, etc.
