On a Higher-Order Difference Equation

open access: yesDiscrete Dynamics in Nature and Society, 2010
We describe in an elegant and short way the behaviour of positive solutions of the higher-order difference equation xn=cxn−pxn−p−q/xn−q, n∈ℕ0, where p,q∈ℕ and c>0, extending some recent results in the literature.

Solvability of some classes of nonlinear first-order difference equations by invariants and generalized invariants

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2019
We introduce notion of a generalized invariant for difference equations, which naturally generalizes notion of an invariant for the equations. Some motivations, basic examples and methods for application of invariants in the theory of solvability of ...

Solvability and representations of the general solutions to some nonlinear difference equations of second order

open access: yesAIMS Mathematics, 2023
We give detailed theoretical explanations for getting the closed-form formulas and representations for the general solutions to four special cases of a class of nonlinear difference equations of second order considered in the literature, present an ...

Existence of meromorphic solutions of first order difference equations [PDF]

open access: yes, 2018
It is shown that if It is shown that if \begin{equation}\label{abstract_eq} f(z+1)^n=R(z,f),\tag{\dag} \end{equation} where $R(z,f)$ is rational in $f$ with meromorphic coefficients and $\deg_f(R(z,f))=n$, has an admissible meromorphic solution ...

On a Difference-Delay Equation

open access: yesJournal of Mathematical Analysis and Applications, 2000
AbstractWe investigate how the behaviour, especially at ±∞, of continuous real solutions f(t) to the equation f(t)=a1f(t+h1)+a2f(t−h2), where a1,a2,h1,h2 are positive real constants, depends on the values of these parameters. Definitive answers are given, except in certain cases when h1/h2 is rational.

Meromorphic solutions of three certain types of non-linear difference equations

open access: yesAIMS Mathematics, 2021
In this paper, the representations of meromorphic solutions for three types of non-linear difference equations of form $ f^{n}(z)+P_{d}(z, f) = u(z)e^{v(z)}, $ $ f^{n}(z)+P_{d}(z, f) = p_{1}e^{\lambda z}+p_{2}e^{-\lambda z} $ and $

Differential-difference equations reducible to difference and q-difference equations

open access: yesComputers & Mathematics with Applications, 2001
AbstractThe paper considers quasi-nonliner differential-difference equations (DDE) of the form which is a representative example of so-called completely integrable DDEs (i.e., DDEs that are reducible to functional equations). This equation is shown to exhibit the “nonstandard” (from the viewpoint of differential equations theory) behavior of solutions.
