Positive Periodic Solutions for Neutral Functional Difference Equations
In this paper, we apply fixed point theorem in a cone to obtain sufficient conditions for the existence of single and multiple positive periodic solutions for a class of neutral functional difference equation. AMS Subject Classifications: 39A10, 39A11.
متن کاملPeriodic Solutions of Second Order Nonlinear Functional Difference Equations
The development of the study of periodic solution of functional difference equations is relatively rapid. There has been many approaches to study periodic solutions of difference equations, such as critical point theory, fixed point theorems in Banach spaces or in cones of Banach spaces, coincidence degree theory, KaplanYorke method, and so on, one may see [3-7,11,13-15] and the references ther...

متن کاملExistence of Positive Periodic Solutions for Neutral Functional Differential Equations
We find sufficient conditions for the existence of positive periodic solutions of two kinds of neutral differential equations. Using Krasnoselskii’s fixed-point theorem in cones, we obtain results that extend and improve previous results. These results are useful mostly when applied to neutral equations with delay in bio-mathematics.
متن کاملTwo Periodic Solutions of Neutral Difference Equations Modelling Physiological Processes
where λ is a positive parameter. Chow [2], Smith and Kuang [13], and many others studied the type of equations or their generalized forms. This type of equations has been proposed as models for a variety of physiological processes and conditions including production of blood cells, respiration, and cardiac arrhythmias [11, 15]. To our best knowledge, few papers are on multiplicity of periodic s...
