Existence of positive periodic solutions for a class of nonautonomous difference equations. <i>Electronic Journal of Differential Equations, 2006</i>(03), pp. 1-18.1072-6691https://hdl.handle.net/10877/13876In this article, we investigate the existence of positive periodic solutions for a class of non-autonomous difference equations. Using the Krasnoselskii 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.Text18 pages1 file (.pdf)enAttribution 4.0 InternationalNonautonomous difference equationsPeriodic solutionKrasnoselskii fixed point theoremNumerical simulationsArticle
