Abstract and Applied Analysis, 2012, vol. 2012, 1-13

Abstract:

The existence results of positive ω -periodic solutions are obtained for the second-order differential equation with delays , where is a ω -periodic function, is a continuous function, which is ω -periodic in , and are positive constants. Our discussion is based on the fixed point index theory in cones.
