A Congruent Property of Gibonacci Number Modulo Prime

open access: yesInternational Journal of Analysis and Applications, 2023
Let a, b ∈ Z and p be a prime number such that a and b are not divisible by p. In this work, we give a congruent property modulo a prime number p of the gibonacci number defined by Gn = Gn−1 + Gn−2 with initial condition G1 = a, G2 = b.

The concept of prime number and the strategies used in explaining prime numbers

open access: yesSouth African Journal of Education, 2020
The teaching of mathematics does not only require the teacher to have knowledge about the subject, but the teacher also needs mathematical knowledge that is useful for the teaching and explaining thereof, as the teacher’s knowledge effects the students ...

Carmichael Numbers with a Prime Number of Prime Factors

open access: yes, 2022
Under the assumption of Heath-Brown's conjecture on the first prime in an arithmetic progression, we prove that there are infinitely many Carmichael numbers $n$ such that the number of prime factors of $n$ is prime.

Prime-Perfect Numbers

open access: yesIntegers, 2012
Abstract.We discuss a relative of the perfect numbers for which it is possible to prove that there are infinitely many examples. Call a natural numberasWe conclude by discussing some related problems posed by Harborth and Cohen.

A Relation between Prime Numbers and Twin Prime Numbers [PDF]

open access: yesMathematical and Computational Applications, 2001
Every mathematician has been concerned with prime numbers, and has metwith mysterious surprises about them. Besides intuition, using empirical methods has an important role to findrelations between prime numbers. A relation between any prime numberand any twin prime number has been obtained.

SanD primes and numbers

open access: yesJ. Integer Seq., 2019
We define S(um)anD(ifference) numbers as ordered pairs $(m,\, m+Δ)$ such that the digital-sum $DS(m(m+Δ))=Δ.$ We consider both the decimal and the binary case. If both $m$ and $m+Δ$ are prime numbers, we refer to SanD {\em primes}. We show that the number of (decimal-based) SanD numbers less than $x$ grows as $c1\cdot x,$ where $c1 = 2/3,$ while the ...

Relatively Prime Detour Domination Number of Some Switching Graphs

open access: yesRatio Mathematica, 2023
In this paper, we introduce the concept of relatively prime detour domination number for switching graph. If a set S ⊆ V is a detour set, a dominating set with at least two elements, and has (deg(u), deg(v)) = 1 for each pair of vertices u and v, then it

Thirty-nine perfect numbers and their divisors

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1986
The following results concerning even perfect numbers and their divisors are proved: (1) A positive integer n of the form 2p−1(2p−1), where 2p−1 is prime, is a perfect number; (2) every even perfect number is a triangular number; (3) τ(n)=2p, where τ(n ...
