EXISTENCE OF PERIODIC SOLUTIONS IN TOTALLY NONLINEAR NEUTRAL DIFFERANCE EQUATIONS WITH VARIABLE DELAY

Positive Periodic Solutions in Neutral Delay Difference Equations

We use Krasnoselskii’s fixed point theorem to obtain sufficient conditions for the existence of a positive periodic solution of the neutral delay difference equation x(n+ 1) = a(n)x(n) + c∆x(n− τ) + g(n, x(n− τ)). AMS Subject Classifications: 39A10, 39A12.

Periodic Solutions for Nonlinear Neutral Delay Integro-differential Equations

In this article, we consider a model for the spread of certain infectious disease governed by a delay integro-differential equation. We obtain the existence and the uniqueness of a positive periodic solution, by using Perov’s fixed point theorem in generalized metric spaces.

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.
