p-adic difference-difference Lotka-Volterra equation and ultra-discrete limit [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
We study the difference-difference Lotka-Volterra equations in p-adic number space and its p-adic valuation version. We point out that the structure of the space given by taking the ultra-discrete limit is the same as that of the p-adic valuation space ...

The 2-adic valuation of the general degree-2 polynomial in 2 variables [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics, 2023
We define the p-adic valuation tree of a polynomial f(x,y) ∈ ℤ[x,y] by which we can find its p-adic valuation at any point. This work includes diverse 2-adic valuation trees of certain degree-two polynomials in two variables.

Narayana sequence and the Brocard–Ramanujan equation [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics, 2023
Let {aₙ}_{n≥0} be the Narayana sequence defined by the recurrence aₙ = aₙ₋₁ + aₙ₋₃ for all n ≥ 3 with initial values a₀ = 0 and a₁ = a₂ = 1. In this paper, we fully characterize the 3-adic valuation of aₙ + 1 and aₙ - 1, and then we find all positive ...

Nontrivial lower bounds for the p-adic valuations of some type of rational numbers and an application for establishing the integrality of some rational sequences [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics, 2023
In this note, based on a certain functional equation of the dilogarithm function, we establish nontrivial lower bounds for the p-adic valuation (where p is a given prime number) of some type of rational numbers involving harmonic numbers. Then we use our

Implicit linear difference equations over a non-Archi-medean ring

open access: yesVisnik Harkivsʹkogo Nacionalʹnogo Universitetu im. V.N. Karazina. Cepiâ Matematika, Prikladna Matematika i Mehanika, 2021
Over any field an implicit linear difference equation one can reduce to the usual explicit one, which has infinitely many solutions ~ one for each initial value.

Connections Between the Completion of Normed Spaces Over Non-Archimedean Fields and the Stability of the Cauchy Equation

open access: yesAnnales Mathematicae Silesianae, 2020
In [12] a close connection between stability results for the Cauchy equation and the completion of a normed space over the rationals endowed with the usual absolute value has been investigated. Here similar results are presented when the valuation of the

A Unique Representation of Cyclic Codes over GR(pn,r)

open access: yesAxioms, 2022
Let R be a Galois ring, GR(pn,r), of characteristic pn and of order pnr. In this article, we study cyclic codes of arbitrary length, N, over R. We use discrete Fourier transform (DFT) to determine a unique representation of cyclic codes of length, N, in ...

Further Results on a Curious Arithmetic Function

open access: yesJournal of Mathematics, 2020
Let p be an odd prime number and n be a positive integer. Let vpn, N∗, and Q+ denote the p-adic valuation of the integer n, the set of positive integers, and the set of positive rational numbers, respectively.

On Periodic Points of the Order of Appearance in the Fibonacci Sequence

open access: yesMathematics, 2020
Let ( F n ) n ≥ 0 be the Fibonacci sequence. The order of appearance z ( n ) of an integer n ≥ 1 is defined by z ( n ) = min { k ≥ 1 : n ∣ F k } .

On the Diophantine Equation z(n) = (2 − 1/k)n Involving the Order of Appearance in the Fibonacci Sequence

open access: yesMathematics, 2020
Let ( F n ) n ≥ 0 be the sequence of the Fibonacci numbers. The order (or rank) of appearance z ( n ) of a positive integer n is defined as the smallest positive integer m such that n divides F m .
