Add to ORKGIn this article, we investigate the existence of positive periodic solutions for a class of non-autonomous difference equations. Using the Kras-noselskii fixed point theorem, we establish sufficient criteria that are easily verifiable and that generalize and improve related studies in the literature. Numerical simulations are presented which support our theoretical results for some concrete models
