Abstract and Applied Analysis, 2013, vol. 2013, 1-5

Abstract:

We present sufficient conditions ensuring the lower and upper functions on the reversed-order for the periodic difference equations. This enables us to obtain the existence of positive periodic solutions of the second-order difference equation where , and are -periodic functions, .
