Second Order Delay Difference Equations With Periodic Boundary Value Problems And Periodic Solutions Of The Monotone Iterative Method

In this paper, we employ monotone iterative technique to study the existence of solutions for second order periodic boundary value problem and periodic solutions of delay difference equations.We consider the following periodic boundary valve problems (PBVPs):where (i.e., f is continuous as a map from the topological space I + R2 into the topological space R (of course the topology on I, will be the discrete topology).In a similar way , we consider the T-periodic solutions of the following delay difference equations:where...
