Existence of Periodic Positive Solutions for Abstract Difference Equations

open access: yesDiscrete Dynamics in Nature and Society, 2011
We will consider the existence of multiple positive periodic solutions for a class of abstract difference equations by using the well-known fixed point theorem (due to Krasnoselskii).

Solvability and Dynamical Analysis of Difference Equations

open access: yesInternational Journal of Analysis and Applications, 2023
We obtain symmetries of a family of difference equations and we prove a relationship between these symmetries and similarity variables. We proceed with reduction and eventually derive formula solutions of the difference equations. Furthermore, we discuss
