On Some Solvable Difference Equations and Systems of Difference Equations [PDF]

open access: yesAbstract and Applied Analysis, 2012
Here, we give explicit formulae for solutions of some systems of difference equations, which extend some very particular recent results in the literature and give natural explanations for them, which were omitted in the previous literature.

Asymptotic Stability of Solutions to a Class of Second-Order Delay Differential Equations

open access: yesMathematics, 2021
We consider a class of second-order nonlinear delay differential equations with periodic coefficients in linear terms. We obtain conditions under which the zero solution is asymptotically stable. Estimates for attraction sets and decay rates of solutions

On the Cauchy Problem for Pseudohyperbolic Equations with Lower Order Terms

open access: yesMathematics, 2023
We consider a class of strictly pseudohyperbolic equations with lower order terms. The solvability of the Cauchy problem in Sobolev spaces with special weights is established. The uniqueness of the solution is proven and estimates are obtained.

Asymptotic Properties of Solutions to Delay Differential Equations Describing Plankton—Fish Interaction

open access: yesMathematics, 2021
We consider a system of differential equations with two delays describing plankton–fish interaction. We analyze the case when the equilibrium point of this system corresponding to the presence of only phytoplankton and the absence of zooplankton and fish

On differential approximations of difference schemes [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Математика. Механика. Информатика, 2021
The concept of the first differential approximation was introduced in the 1950s for the analysis of difference schemes by A. I. Zhukov  and then was used to study the quality of difference schemes approximating equations in partial derivatives.

On a class of nonlinear rational systems of difference equations

open access: yesAIMS Mathematics, 2023
In this paper, we construct and formulate the solutions and periodicity character of the following nonlinear rational systems of difference equations: $ \begin{equation} S_{n+1} = \dfrac{T_{n} S_{n-2}}{S_{n-2} + T_{n-1}},\quad T_{n+1} = \dfrac{S_{n ...
