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 ...

Existence of a unique bounded solution to a linear second-order difference equation and the linear first-order difference equation

open access: yesAdvances in Difference Equations, 2017
We present some interesting facts connected with the following second-order difference equation: x n + 2 − q n x n = f n , n ∈ N 0 , $$x_{n+2}-q_{n}x_{n}=f_{n},\quad n\in \mathbb{N}_{0}, $$ where ( q n ) n ∈ N 0 $(q_{n})_{n\in\mathbb{N}_{0}}$ and ( f n )

Note on the binomial partial difference equation

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2015
Some formulas for the "general solution" to the binomial partial difference equation $$c_{m,n}=c_{m-1,n}+c_{m-1,n-1},$$ are known in the literature. However, it seems that there is no such a formula on the most natural domain connected to the equation ...

The Beverton-Holt q-difference equation. [PDF]

open access: yesJ Biol Dyn, 2013
The Beverton–Holt model is a classical population model which has been considered in the literature for the discrete-time case. Its continuous-time analogue is the well-known logistic model.

Existence Results for Nonlinear Fractional Difference Equation

open access: yesAdvances in Difference Equations, 2011
This paper is concerned with the initial value problem to a nonlinear fractional difference equation with the Caputo like difference operator. By means of some fixed point theorems, global and local existence results of solutions are obtained.

On the solutions of a higher‐order difference equation in terms of generalized Fibonacci sequences [PDF]

open access: yes, 2016
This paper deals with the solutions, stability character, and asymptotic behavior of the difference equation xn+1=αβ+γxn−k;n∈N0, where N0=N∪0,α,β,γ,∈R∗+ and the initial values x−k,x−k + 1,…,x0 are nonzero real numbers, such that their solutions are ...

Symmetries of the Hirota Difference Equation [PDF]

open access: yes, 2017
Continuous symmetries of the Hirota difference equation, commuting with shifts of independent variables, are derived by means of the dressing procedure. Action of these symmetries on the dependent variables of the equation is presented.

On a solvable nonlinear difference equation of higher order

open access: yesTurkish Journal of Mathematics, 2018
In this paper we consider the following higher-order nonlinear difference equation xn = αxn−k + δxn−kxn−(k+l) βxn−(k+l) + γxn−l , n ∈ N0, where k and l are fixed natural numbers, and the parameters α , β , γ , δ and the initial values x−i , i = 1, k + l ,

Entwined Paths, Difference Equations and the Dirac Equation [PDF]

open access: yes, 2002
Entwined space-time paths are bound pairs of trajectories which are traversed in opposite directions with respect to macroscopic time. In this paper we show that ensembles of entwined paths on a discrete space-time lattice are simply described by coupled

On a nonlinear second-order difference equation

open access: yesJournal of Inequalities and Applications, 2022
We study a nonlinear second-order difference equation which considerably extends some equations in the literature. Our main result shows that the difference equation is solvable in closed form. Some applications of the main result are also given.
